refactor(cpufeat): add macro to simplify is_feat_xx_present

In this patch, we are trying to introduce the wrapper macro
CREATE_FEATURE_PRESENT to get the following capability and
align it for all the features:

-> is_feat_xx_present(): Does Hardware implement the feature.
-> uniformity in naming the function across multiple features.
-> improved readability

The is_feat_xx_present() is implemented to check if the hardware
implements the feature and does not take into account the
ENABLE_FEAT_XXX flag enabled/disabled in software.

- CREATE_FEATURE_PRESENT(name, idreg, shift, mask, idval)
The wrapper macro reduces the function to a single line and
creates the is_feat_xx_present function that checks the
id register based on the shift and mask values and compares
this against a determined idvalue.

fix(plat/marvell/a3k): reset GIC before resetting via CM3 secure coprocessor

Add code that acknowledges all SoC interrupts and resets the Generic
Interrupt Controller before resetting the SoC via the Cortex-M3 secure
coprocessor.

Recall that Turris MOX has a HW bug wherein a SoC reset initiated by
writing the magic value to the North Bridge Warm Reset register may
randomly freeze the board.

Back in 2021 we introduced the CM3_SYSTEM_RESET build option for the
Armada 3700 platform, which, when enabled, adds code to the PSCI reset
handler so that the SoC reset is done by requesting the firmware in the
Cortex-M3 secure coprocessor to do it, instead of writing the Warm Reset
register.

The secure coprocessor firmware tried various things to put the board
into a state where the SoC reset circuit would work correctly. This
managed to fix the issue for some boards, but not for all of them.

Another considered method to overcome this issue was to reset all the
SoC peripheral controllers one by one by writing to specific registers,
instead of triggering the SoC reset circuit via the Warm Reset register.
This method was not used because until now, there was one peripheral
that I could not find a way how to reset properly: the Generic Interrupt
Controller (GIC).

After 3 years I have finally found a way how to reset the GIC, and it
needs to be done by the main processor, before the secure coprocessor
resets the main processor.

refactor(tc): add platform specific DT files

Currently, the DT binding uses the file 'tc.dts' as a central place for
all TC platforms. And the variables (for different platforms, or FVP vs
FPGA, etc.) are maintained in 'tc_vers.dtsi'.

This patch renames 'tc.dts' to 'tc-base.dtsi' and creates an individual
.dts file for every platform. The purpose is to use 'tc-base.dtsi' for
maintaining common DT binding and every platform's specific definitions
will be moved into its own .dts file. This is a preparation for
sequential refactoring.

It changes to include the header files in platform DTS files but not in
the 'tc-base.dtsi'. This can allow 'tc-base.dtsi' is general enough and
platform DTS files covers platform specific defintions.

fix(tc): enable FEAT_MTE2

Commit c282384db ("refactor(mte): remove mte, mte_perm") removes the
option FEAT_MTE and introduces FEAT_MTE2 option. Afterwards, the
FEAT_MTE2 option is missed on the TC platform and the feature is
disabled. As a result, it causes the panic in secure world.

This patch enables the FEAT_MTE2 option for TC platform to allow the
secure world can access the MTE registers properly.

build: remove `MAKE_BUILD_STRINGS` function

This function causes the build message to be generated and compiled in
two different ways, with one way done inside `build_macros.mk` and the
other done inside `windows.mk`, mostly because it's done by generating
the C file on the command line.

We can instead replace this whole build message generation sequence with
a simple standard C compilation command and a normal C file.

feat(imx): add helper to take params from BL2

So far the i.MX BL31 doesn't take any parameters. This means the BL32
image base address and whether or not a BL32 image is used at all has to
be hardcoded in BL31.

This adds a helper function that allows to take params from BL2 safely.
On i.MX BL2 is usually U-Boot SPL which passes random values in arg0,
so make sure arg0 is within the internal SRAM range before accessing it
as a pointer. Also make sure arg0 is sufficiently aligned and the header
type and version is correct.
