The current Generic Interrupt Controller (GIC) driver makes use of the
multi-level interrupt mechanism and `irq_nextlevel` public interface.
This is a less-than-ideal implementation for the following reasons:
1. The GIC is often used as the main interrupt controller for the
Cortex-A and Cortex-R family SoCs and, in this case, it is not a 2nd
level interrupt controller; in fact, it is the root interrupt
controller and therefore should be treated as such.
2. The only reason for using `irq_nextlevel` here is to interface the
architecture implementation to the interrupt controller functions.
Since there is no nesting or multiple instances of an interrupt
controller involved, there is really no point in adding such an
abstraction.
3. 2nd level topology adds many unnecessary abstractions and results
in strange coding artefacts as well as performance penalty due to
additional branching.
This commit refactors the GIC driver interface as follows:
1. Remove the current GIC driver interface based on the multi-level
interrupt mechanism and the `irq_nextlevel` public interface.
2. Define the GIC driver interface in
`include/drivers/interrupt_controller/gic.h` and allow the arch
implementation to directly invoke this interface.

If IO APIC is in logical destination mode, local APICs compare their

This patch programs LDR in xAPIC mode to support IO APIC logical mode.
The local APIC ID from local APIC ID register can't be used as the
'logical APIC ID' because LAPIC ID may not be consecutive numbers hence
it makes it impossible for LDR to encode 8 IDs within 8 bits.

This commit fixes incorrect Cortex-R interrupt lock, unlock and state
check function implementations.
The issues can be summarised as follows:
1. The current implementation of 'z_arch_irq_lock' returns the value
of CPSR as the IRQ key and, since CPSR contains many other state
bits, this caused 'z_arch_irq_unlocked' to return false even when
IRQ is unlocked. This problem is fixed by isolating only the I-bit
of CPSR and returning this value as the IRQ key, such that it
returns a non-zero value when interrupt is disabled.
2. The current implementation of 'z_arch_irq_unlock' directly updates
the value of CPSR control field with the IRQ key and this can cause
other state bits in CPSR to be corrupted. This problem is fixed by
conditionally enabling interrupt using CPSIE instruction when the
value of IRQ key is a zero.
3. The current implementation of 'z_arch_is_in_isr' checks the value
of CPSR MODE field and returns true if its value is IRQ or FIQ.
While this does not normally cause an issue, the function can return
false when IRQ offloading is used because the offload function
executes in SVC mode. This problem is fixed by adding check for SVC
mode.

Use of the _current_cpu pointer cannot be done safely in a preemptible
context. If a thread is preempted and migrates to another CPU, the
old CPU record will be wrong.
Add a validation assert to the expression that catches incorrect
usages, and fix up the spots where it was wrong (most important being
a few uses of _current outside of locks, and the arch_is_in_isr()
implementation).
Note that the resulting _current expression now requires locking and
is going to be somewhat slower. Longer term it's going to be better
to augment the arch API to allow SMP architectures to implement a
faster "get current thread pointer" action than this default.
Note also that this change means that "_current" is no longer
expressible as an lvalue (long ago, it was just a static variable), so
the places where it gets assigned now assign to _current_cpu->current
instead.

These have been replaced by the appropriate call to
gpio_pin_interrupt_configure(). While the disable function could be
implemented using the new functionality, the enable function cannot
because the interrupt mode is not available. Consequently we cannot
replace these with equivalent functionality using the legacy API.
Clean up the internal implementation by removing the inaccessible
port-based enable/disable feature, leaving the pin-based capability in
place.

The public API for GPIO flags should use unsigned values, and for
MISRA compliance the size should not be platform-dependent. Add a
typedef for generic flags.
Also add typedefs for pin indexes and devicetree flags so these can
be safely recorded from devicetree property values without risking
loss of information if more flags are added in the future.

Extend the physical level GPIO_OUTPUT_{HIGH,LOW} configuration with

gpio_pin_interrupt_configure() is invoked from within
gpio_pin_configure() to support legacy code that combines pin and
interrupt configuration. Expressing a disabled interrupt by a zero
value for interrupt flags causes this invocation to disable interrupts
when the intent is to change only a pin configuration, such as pull
direction.
Support a distinction between explicitly disabling interrupts and
leaving the interrupt configuration unchanged.

stm32_exti_enable was returning errors on line > 32 or line pointing
to non implemented line. Both conditions are hard-coded, hence there
is no use to detect them dynamically in the code.
Check them with assert. As a consequence, function could now be void.
Additionally, enable exti irq line only if both checks are passed.

Since it is now possible to disable/re-enable interrupts and
also to reconfigure an already configured interrupt, it is
now required to clear non requested triggers.
While it is not strictly requested, triggers are also cleared
when interrupt is disabled (assuming trigger should be configured
when interrupt is enabled).

fixup exti
A large number of sensor drivers specify GPIO_INT_DEBOUNCE to request
a debounced signal; in practice the debounce may be performed by
external components on the board. Historically this flag was ignored
on the many GPIO peripherals that do not support hardware debouncing.
Document that this flag is an exception to the normal rule that
unsupported features should be rejected by gpio_pin_configure.
