NPCX WIMU CR_SIN is used to wake up soc from NPCX sleep power state.
The wake-up IRQ enabled when UART init. It causes the wake-up IRQ to
generate many extra interrupt events, which causes the system too busy
to handle other events. This PR moves the UART wake-up IRQ enabling
from UART init to npcx_power_enter_system_sleep() to avoid the
interrupt storm.

Set the defalut value of SYS_CLOCK_HW_CYCLES_PER_SEC Kconfig option
from the Device Tree. The `clock-frequency` property of the DT cpu@0
node is a single source of truth defining the CPU frequency. This is
the value used e.g. by all Atmel drivers.
For Atmel SAM family CPU clock is currently the only supported system
clock source. Ensure that kernel understanding of the hardware clock
frequency is the correct one.

MPS2 AN521 is a dual (Cortex-M33) core where the two cores
have different capabilities. E.g CPU0 implements TrustZone-M,
while CPU1 implements the FPU. Therefore we introcude separate
Kconfig symbols for the two SoC variants, and use these to
select the different Cortex-M capabilities. We also update
the definitions of __MPU/FPU/SAU/DSP variant in soc.h to make
them get the value from the Kconfig settings, directly.

We should gurantee that we do not use SRAM during Zephyr early
boot, until SystemInit has returned. This commit aims to ensure
that SystemInit will be branched to, without first pushing args
to stack, even when no optimizations are selected. We chose to
define z_platform_init in assembly directly (instead of using
inline assembly) as it appears to be a cleaner design.

This is a follow-up to commit 60d9988401.
Add a third option for the HFXO capacitance that keeps the default
value of the XOSC32MCAPS register untouched. The message in the above
commit incorrectly claimed that external load capacitors for HFXO
(the reset value of the XOSC32MCAPS register) was the configuration
in effect before. In fact, the register value was modified during
the device trimming in the SystemInit() function to use the internal
capacitors, and that is the configuration required for proper RADIO
operation on nRF5340 DK, for instance.

directly from Kconfig instead of generated Kconfig files.
This has the benefit that it is no longer necessary to generate Kconfig

Also this cleans up the doc/CMakeLists.txt and ensures that the

NPCX7 variants allocate code RAM either at 0x10070000 or 0x10090000.
The MPU requires addresses and region sizes to be aligned, so the
generic cortex_m/arm_mpu_regions.c results in an ineffective setup with
the addresses above.
This adds a custom mpu_regions setup for the npcx7, which covers both
available sizes, resulting in these two possible setups:
- 192kB devices
Code ram: 0x10090000 to 0x100bffff
MPU region: 0x10080000 to 0x100bffff (256k)
- 320kB devices
Code ram: 0x10070000 to 0x100bffff
MPU region 0: 0x10040000 to 0x1007ffff (256k)
MPU region 1: 0x10080000 to 0x100bffff (256k)
In both cases MPU data RAM setting is from 0x200c0000 to 0x200cffff,
matching the generic Cortex-m setup.

Commit f5c6afeccb attempted to avoid
accessing lpc55xxx flash registers in nonsecure mode by conditionalizing
part of the SoC clock initialization routine on whether the flash driver
was enabled. This caused secure applications without the flash driver
enabled (e.g., hello_world on lpcxpresso55s69_cpu0) to not boot or show
any console output. Fix this by changing the condition to depend on
whether we are building a nonsecure image.

Zephyr kernel masks interrupts before calling the SoC PM
sleep entry point. On the Cortex-Mx family this prevents
wake from peripheral interrupts. The SoC PM layer requires
interrupts to wake the SoC and must prevent the CPU from
vectoring to an interrup until PM exit. The SoC does this
by setting ARM NVIC PRIMASK to 1 and BASEPRI to 0. On
return to the kernel SoC sets PRIMASK to 0 allowing ISR's
to fire. In addition the MEC HW only clears its peripheral
sleep enables if the CPU vectors to an ISR. On wake we
clear the MEC PCR sleep control register which clears all
the peripheral sleep enables so peripherals will be active
before exiting the SoC PM layer.
