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.

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.

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.

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

Before introducing the code for ARM64 (AArch64) we need to relocate the
current ARM code to a new AArch32 sub-directory. For now we can assume
that no code is shared between ARM and ARM64.
There are no functional changes. The code is moved to the new location
and the file paths are fixed to reflect this change.

Updates the MCUXpresso SDK to version 2.5.0 for applicable SoCs.
Wireless (KW*) and legacy (KL25) SoCs were not included in this
MCUXpresso SDK release and are therefore not updated here.
New in this release is SoC-level and board-level support for external
xip flash in the i.MX RT family.
For RT1050, we are now using the MCUXpresso SDK for the EVKB version of
the board, which correponds to an upgrade from A0 to A1 silicon.
However, we don't yet have Kconfigs in place to support A1 silicon part
numbers, and therefore add a simple cmake hack to convert A0 part
numbers to A1 part numbers.
The SDK flash driver interface also changed slightly in this release,
and thus the zephyr flash shim driver is updated accordingly.
