fix(imx93): trdc: restrict BLK_CTRL_S_AONMIX to secure world

Configure the TRDC to restrict access to BLK_CTRL_S_AONMIX to secure
world only. So the A55 resume entry in RVBARADDR0 can't be modified
by untrusted applications.

refactor(console): consolidate console runtime switch

Refactor console_flush() and console_switch_state(CONSOLE_FLAG_RUNTIME)
to bl31_main(). This has been done per the recommendation in TF-A
mailing list. These calls need to be the last calls, after any runtime
initialization has been done, before BL31 exits.

All platforms that override the generic implementation of
bl31_plat_runtime_setup() have been refactored. The console_flush()
and console_switch_state() calls have been removed as they become
part of bl31_main() function.

Any platform that don't need to make any change to the generic (weak)
implementation of bl31_plat_runtime_setup() don't need to override it
in their platforms.

refactor(imx): console runtime switch on bl31 exit

Flush the FIFO before switching to runtime. This is so that there are
no lingering chars in the FIFO when we move to the runtime console.

TF-A plans to refactor the console_Switch_state(CONSOLE_FLAG_RUNTIME)
and console_flush() calls and make them the last calls in bl31_main()
(before BL31 exits). Until then they are being left as the last calls
in bl31_plat_runtime_setup() for testing before refactoring.

This patch affects the Freescale/NXP SoCs imx93, imx8qm and imx8qx.

feat(imx93): optionally take params from BL2

Optionally take params from BL2 to offer more flexibility to BL2 on
where and if a BL32 image is expected. This uses imx_bl31_params_parse()
to check if arg0 can safely be accessed as a pointer and actually
contains a bl_params_t structure. If not, the hardcoded parameter
values are used as before.

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.
