Use 32bit operations for id field in intel64_cpu_s which is int type.
This fixes an error that appears when enabling some debug options:
`Error: operand size mismatch for `movq'``

Intel64 can now boot application cores which is needed for SMP
IMPORTANT: CONFIG_BOARD_LOOPSPERMSEC must be properly configured,
otherwise AP boot sequence can fail due too short delays during the AP startup

Use GS base regsiter to store reference to CPU private data.
Then we can easily refer to private CPU data using the GS segment.

It turns out that the D0 core of the BL808 has an IRQ that represents all interrupt sources for the M0 core. This change uses this IRQ to access these sources, eliminating the need for IPC between M0 and D0.

Disable sincos optimization for all functions in this file,
otherwise gcc would generate infinite calls.
Refer to gcc bug 46926.
-fno-builtin-sin or -fno-builtin-cos can disable sincos optimization,
but these two options do not work inside optimize pragma in-file.
Thus we just enforce -O0 when compiling this file.

on ACRN hypervisor obtaining frequency from CPUID seems to be broken,
so we have to specify this value from Kconfig.
If frequency autodetection is enabled but the returned data are
incorrect - crash early.

- This PR adds the GPIO Driver for BL808 SoC. This will be used by the upcoming LED Driver for Ox64 Board.
- The BL808 GPIO Driver was derived from the NuttX Driver for BL602 GPIO

Squashed:
Initial settings for MCPWM Capture on board level
Created lower half files - compilation ok
Using capture debug features. Simple example on fops works
Successful duty and freq calculation
Documentation update
Fixed and added interupt capabilities for all 3 capture channels
Cleaned defconfig
Renamed macros, added S3 options and moved arch source to common dir
Added support for ESP32S3
Added capture example to defconfig and renamed
For now, IOB off-loading in the wireless driver was removed because
it is not compatible with SMP-enabled devices, which is valid for
ESP32-S3. The performance gain by keeping the IOB off-loading in
the wireless drivers is not exceeded by keeping the flat buffer
approach and enabling `CONFIG_SMP=y`.
purpose:
1 sched_lock is very time-consuming, and reducing its invocations can improve performance.
2 sched_lock is prone to misuse, and narrowing its scope of use is to prevent people from referencing incorrect code and using it
