e4538c6807 Bluetooth: HCI: Re-organize vendor read static address handling
Add header definition for bt_read_static_addr function. Declaring it
without a header definition will not give any compilation error when
function definition changes.
Refactor nRF SoC specific code into nRF specific source files and
provide weak definitions when these are not implemented. This will make
it easier to add handlers per vendor.

50519ce7ba interrupt_controller: gic: Refactor GIC driver interface
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.

87b65c5ac2 interrupt_controller: program local APIC LDR register for xAPIC
If IO APIC is in logical destination mode, local APICs compare their
logical APIC ID defined in LDR (Logical Destination Register) with
the destination code sent with the interrupt to determine whether or not
to accept the incoming interrupt.

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 patch chooses 0 for BSP, and for APs, cpu_number which is the index
to x86_cpuboot[], which ultimately assigned in z_smp_init[].

These have been replaced by the appropriate call to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.

port-based enable/disable feature, leaving the pin-based capability in
place.

2b150bff4f gpio: avoid disabling interrupts when supporting legacy code
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.
