Adds a hidden config symbol HAS_MCUX_FLEXSPI selected by NXP SoCs when
the FlexSPI peripheral is present. It will be used as a dependency for a
new FlexSPI flash driver to prevent users from accidentally enabling the
driver on platforms that don't have the necessary hardware.

This changes the timing functions to use TSC to gather
timing information instead of using the timer for
scheduling as it provides higher resolution for timing
information.

The strategy used in z_heap_aligned_alloc() was to allocate an extra
align-sized memory block for storing a pointer to the memory heap.
This is wasteful in terms of memory usage when alignment is larger
than a pointer width. A loop is needed to find the initial memory
start when freeing it which isn't optimal either.
Instead, let's have sys_heap_aligned_alloc() rewind a pointer after
it is aligned to make just enough room for storing our heap reference.
This way the heap reference is always located immediately before the
aligned memory and any unused memory is returned to the heap.
The rewind and alignment values may coincide in which case only
the alignment is necessary anyway.

This wait on @ prompt was added in
fa3d586483.
The situation were the @ prompt is never received should not occurs,
however it's definitively safer to catch it instead of having a
deadlock.

Fix sys_read32 return value from uint16_t to uint32_t.
Current implementation causes read/modify/write of 32bit

This targets was previously enabling PM but the code was doing nothing
because the logic was under an unsatisfied ifdef condition.

Change subsystem to use struct pm_state with substate-id instead of
using only the power state category.

There are platforms that have multiple states that maps to a specific
Zephyr power state. To accommodate this sort of situation this commit
adds an additional property to a power state that can be used by the
platform.
The power state now consists of two properties, a category and a
substate-id. The former property is the current power state.
