Mostly SoC initialization and some kernel subsystems, but also some
device drivers like the interrupt controllers.

This is the last step before obsoleting DEVICE_DEFINE() and
DEVICE_INIT_CONFIG_DEFINE().

Rename it to DEVICE_DEFINE() so that it fits in the 'device' namespace.

Rename it to DEVICE_INIT_CONFIG_DEFINE(), because (a) it was not fitting
in any namespace and (b) it is not used to declare, but rather define a
object.

The sys_mem_safe_write_to_text_section() now always fails in XIP
systems, since their .text section is in ROM.

Put initialization priorities as device driver Kconfig
parameter.
Initialization priority value for each platform is defined
in the platform Kconfig file.
Drivers and platform code use SYS_DEFINE_DEVICE to add
and initialization function.

Introduces the following routines to provide safe access to memory:
_mem_probe()
_mem_safe_read()
_mem_safe_write()
_mem_safe_write_to_text_section()
Those routines will return an error if the memory is not accessible rather
than potentially crash.
This implementation is based on the image's boundaries; thus it allows
read/write access to the data/bss/init sections and read access only to
the text/rodata sections. All other memory is considered invalid, even
if addressable. This includes the leftover from the RAM at the end of
the image, since there is no support for using it (e.g. there is no
dynamic allocator).
