Cleanup and preparation commit for linker script generator.
Zephyr linker scripts provides start and end symbols for each larger
areas in the linker script.
The symbols _image_text_start and _image_text_end sometimes includes
linker/kobject-text.ld. This mean there must be both the regular
__text_start and __text_end symbols for the pure text section, as well
as <group>_start and <group>_end symbols.
The symbols describing the text region which covers more than just the
text section itself will thus be changed to:
_image_text_start -> __text_region_start
_image_text_end -> __text_region_end

Cleanup and preparation commit for linker script generator.
Zephyr linker scripts provides start and end symbols for each larger
areas in the linker script.
The symbols _image_rom_start and _image_rom_end corresponds to the group
ROMABLE_REGION defined in the ld linker scripts.
The symbols _image_rodata_start and _image_rodata_end is not placed as
independent group but covers common-rom.ld, thread-local-storage.ld,
kobject-rom.ld and snippets-rodata.ld.
This commit align those names and prepares for generation of groups in
linker scripts.
The symbols describing the ROMABLE_REGION will be renamed to:
_image_rom_start -> __rom_region_start
_image_rom_end -> __rom_region_end
The rodata will also use the group symbol notation as:
_image_rodata_start -> __rodata_region_start
_image_rodata_end -> __rodata_region_end

Cleanup and preparation commit for linker script generator.
Zephyr linker scripts provides start and end symbols for each section,
and sometimes even size and LMA start symbols.
Generally, start and end symbols uses the following pattern, as:
Section name: foo
Section start symbol: __foo_start
Section end symbol: __foo_end
However, this pattern is not followed consistently.
To allow for linker script generation and ensure consistent naming of
symbols then the following pattern is introduced consistently to allow
for cleaner linker script generation.
Section name: foo
Section start symbol: __foo_start
Section end symbol: __foo_end
Section size symbol: __foo_size
Section LMA start symbol: __foo_load_start
This commit aligns the symbols for _data_ram/rom to other symbols and in
such a way they follow consistent pattern which allows for linker script
and scatter file generation.
The symbols are named according to the section name they describe.
Section name is `data`
A new group named data_region is introduced which instead spans all the
input and output sections that was previously covered by
__data_ram_start, __data_ram_end, and __data_rom_start.
The following symbols are aligned in this commit:
- __data_ram_start -> __data_region_start
- __data_ram_end -> __data_region_end
- __data_rom_start -> __data_region_load_start
The following new symbols are introduced so that the data section is
aligned with other sections:
- __data_end
- __data_start
value identical to __data_region_start but describes start of
the section.

As some privilege SoCs want to customize the entry point, they should

Current location options for linker source files includes init and
noinit ram data, but only a noinit ram section. This makes it impossible

rv32m1_vega don't boot due to device init ordering and changes with the
device model. The soc code is looking for a device pointer for the
intmux. Change to using DEVICE_DT_GET here as that will ensure we get
a valid pointer and by the time we need to utilize the pointer the
intmux driver will have been initialized and thus the device pointer
will be ready.
Also set BUILD_OUTPUT_HEX since we utilize openocd to flash and west
flash is looking for a hex file for openocd targets.
