The macro used in an assert statement in the `sys_mm_drv_page_phys_get()`
function was using an older version of the naming scheme, fixed now.

Removed the unneccessary casts in the functions to remove warnings
during build for SoCs using RAT. Functionality reamins the same,

Added Region based Address Translation (RAT) module driver. Required by
a few Texas Instruments SoCs to fucntion. Uses
sys_mm_drv_page_phys_get() API with device_map() for address translation.

In case of remapped reference counter for physical page
is differ to zero, but TLB entry for virtual address equal to
physical address will be disabled. Valid entry will be somewhere
in virtual space where particular physical page is remapped.
Since in adsp_mm_save_context() routine we go through physical
memory range, we need to include these pages in context save loop.

The initial implementation was broken during improvements.
There was incorrect assumption that all pages are unmapped at
initials state. In reality at the beginning whole memory is
powered on, so we should mark all pages as mapped. Later in
initialization code unused pages are unmapped and if after this
some banks become empty (all pages unmapped), the power is
switched off.

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

temporary_table is a trivial copy of virtual_memory_regions, it isn't
clear why it's needed. All the more that it's freely mixed with
virtual_memory_regions itself. Also change a variable name to avoid
confusion and improve indentation.

There are various call to z_soc_cached_ptr() which returns values
in the cached address space and are stored in temporary variables
that are not marked as in the cached address space. This results
in sparse complaining about discarding the cached address space
attribute. These temporary variables are then passed to other
internal memory management related functions which do not have
the concept of cached address space (as it is currently Xtensa
specific). Because of this, we cannot change the signature of
these functions. Instead, we force a change of address space
when those temporary variables are being assigned to suppress
sparse warnings.

Remapping by default can confuse things that dynamically manage RAM,
such as newlib heap - since unused memory will be powered off by
default. So this patch shields this behaviour behind a non-default
Kconfig.
