It doesn't make sense to keep the aarch32 directory in the
'arch/arm/core' directory as the aarch64 has been moved out.
This commit introduces the following major changes.
1. Move all directories and files in 'arch/arm/core/aarch32' to
'arch/arm/core' and remove the 'arch/arm/core/aarch32' directory.
2. Move all directories and files in 'arch/include/aarch32' to
'arch/include' and remove the 'arch/include/aarch32' directory.
3. Remove the nested including in the 'arch/include/kernel_arch_func.h'
and 'arch/include/offsets_short_arch.h' header files.
4. Change the path string which is influenced by the changement 1
and 2.

NMI_INIT() is now a no-op, so remove it from all SoC code. Also remove
the irq lock/unlock pattern as it was likely a cause of copy&paste when
NMI_INIT() was called.

To be consistent with the current NXP clocking scheme,
move the LPADC clocking code to the SOC files where
all of the other peripheral clocking is done.
Also remove any other SOC-specific code to the
respective SOC file and out of this driver.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Use CMSIS SystemInit for all NXP iMX.RT SOCs, to simplify initialization
flow, and remove redundant code where possible.
Introduce Kconfigs to disable Cache at boot, since SystemInit will enable
code cache on these platforms, which may be undesirable behavior.

Convert NXP LPC SOCs to use CMSIS SystemInit, and remove redundant code
where it exists. This will enable initialization flows to be more
standardized across all platforms.
Since LPC54xxx and LPC55xxx series enables SRAM banks in SystemInit,
provide Kconfigs to bypass this setting and keep additional SRAM
banks unclocked.

1. Move the defines from usb_dc_mcux.h to usb_device_config.h
and fsl_os_abstraction.h. These headers are used by
the SDK USB driver. usb_dc_mcux.h header file is not longer
needed and hence deleted.
2. Delete the Zephyr implementation of the usb_device_struct
driver and use the one implemented inside the SDK USB
driver. This requires updating the references to
usb_device_struct inside the USB driver
3. Move defines and structures used by the driver
out of the header file that is included by the SDK and
into the MCUX USB driver.
4. Use end point defines provided by Zephyr instead of adding
them locally.
5. Add a Kconfig to set the thread stack size
6. Move code to enable interrupts back to usb_attach function.
Interrupts should be enabled after the init is successful,
else we see errors of the ISR getting called before the
init is complete causing Faults
6. Update west.yml to update the NXP HAL to get the updated
SDK USB driver.

A Cortex-M specific function (sys_clock_isr()) was defined as a weak
function, so in practice it was always available when system clock was
enabled, even if no Cortex-M systick was available. This patch
introduces an auxiliary Kconfig option that, when selected, the ISR
function gets installed. External SysTick drivers can also make use of
this function, thus achieving the same functionality offered today but
in a cleaner way.

Add watchdog support to the mimxrt685 platform.
The mimxrt685 platform is excluded from the watchdog
test case because the test case uses variables in the

but the rt685 does not retain this memory through a
