This aligns the SoC initialization with the one in SOF,
especially the manipulation of clock control and power control
registers. These registers are not entirely the same across
CAVS versions, so we need to deal with them according to
which version we are building for. This also consolidates
the macros for these registers to the one provided by SOF
(soc/shim.h) to avoid duplication. Another note is that
the usage of clock gating bit was not correct. In SOF,
clock gating of SoC cores should be allowed but the old code
in Zephyr prevented clock gating, which has the potential to
prevent the whole DSP from going into low power mode.

The wall clock timer is not (per documentation) part of the
"timestamping" register set on the DSP. And its counter and
comparator registers work fine always. But if the DSP isn't set as
the "owner" of the timestamp hardware, wall clock interrupts never
arrive.
Also grab the PLL ownership too, because SOF already does anyway.
While we don't have a dynamic clock driver yet, we will surely want
one soon and will needt this.

These windows control host visibility of the trace output buffer. The
buffer itself is writable memory always, but until we get to the
register init the host can't see them. Since they contain
printk/logging output, they REALLY need to be initialized earlier than
anything else.
Also remove a rogue memset of the trace buffer. That buffer is
already being initialized in a lazy-evaluated way by the trace output
code, and blowing it away here has the effect of forgetting anything
earlier code was trying to log!

For IMX, for timer interrupt, the interrupt handler
was not the correct one executed and that’s because
the handlers were not at the expected address.
For IMX the size constraint of the interrupt vector
table entry is 0x1C bytes of code, less than usual.
I've added a small indirection to bypass this size
constraint and moved the default handlers to the end
of vector table, renaming them to
_Level\LVL\()VectorHelper.

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.
