For HPET devices, configure it with fixed delivery mode because HPET
timer interrupt is needed to fuel the scheduler for all CPUS.
For all other type of devices, like UART, I2C, GPIO, Ethernet, etc.
configure them as lowest priority delivery mode, in which IO APIC
delivers the interrupt to the processor core that is executing at the
lowest priority among all the processors listed in the specified
destination. In this case, the device drivers can avoid the trouble of
handling repeated interrupts delivered to all CPUS.

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[].

Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.
Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.
To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:
- emit macros for all existing nodes in gen_defines.py, regardless
of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

Add API for recovering an I2C bus. This API can be used to recover
from situations where the I2C master and one or more I2C slaves are
out of synchronization (e.g. if the I2C master was reset in the middle
of an I2C transaction or if a noise pulse was induced on the SCL
line).

init_fn is not anymore part of struct device, so let's test instead the

When the device driver model got introduced, there were no concept of
SYS_INIT() which can be seen as software service. These were introduced
afterwards and reusing the device infrastructure for simplicity.
However, it meant to allocate a bit too much for something that only
required an initialization function to be called at right time.
Thus refactoring the devices structures relevantly:
- introducing struct init_entry which is a generic init end-point
- struct deviceconfig is removed and struct device owns everything now.
- SYS_INIT() generates only a struct init_entry via calling
INIT_ENTRY_DEFINE()
- DEVICE_AND_API_INIT() generates a struct device and calls
INIT_ENTRY_DEFINE()
- init objects sections are in ROM
- device objects sections are in RAM (but will end up in ROM once they
will be 'constified')
It also generate a tiny memory gain on both ROM and RAM, which is nice.
Perhaps kernel/device.c could be renamed to something more relevant.

INLINE is a very common macro, just like MAX or MIN.

The DS3231 is an I2C real-time clock with internal temperature
compensated oscillator, maintaining civil time to 1 s precision with
nominal 2 ppm accuracy from 0-40 Cel.
The basic functionality is exposed as a counter that is always running
at 1 Hz. Much more functionality is exposed as driver-specific API,
including the ability to translate between the time scale of the DS3231
and the time scale of the Zephyr uptime clock. This allows correlation
of events in the system clock to UTC, TAI, or whatever time scale is
used to maintain the DS3231.

Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.
There are a few exceptions:
- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
would require more time to convert than I have at the moment. For the
sake of expediency, just inline the DT_HAS_DRV_INST expansion for
now in these cases.
- SoC drivers which are explicitly single-instance (like the nRF SAADC
driver). Again for the sake of expediency, drop a BUILD_ASSERT in
those cases to make sure the assumption that all supported SoCs have
at most one available instance is valid, failing fast otherwise.

ARC_MPU_VER 2 has a strong requirement in
