style(fwu): change the metadata fields to align with specification

Change the names of some FWU metadata structure members to have them
align with the wording used in the corresponding specification. Use
the GUID type instead of UUID as the fields described in the
specification are GUIDs. Make corresponding changes to the code that
accesses these fields. No functional changes are introduced by the
patch.

feat(st): add logic to boot the platform from an alternate bank

In a few scenarios, there is a need to boot the platform from an
alernate bank which is not the active bank. Call the API
fwu_get_alernate_boot_bank() to select an alternate bank to boot the
platform from. Calling this API function might be required in a couple
of cases. One, in the unlikely scenario of the active bank being in an
invalid state, or if the number of times the platform boots in trial
state exceeds a pre-set count.

Also add a debug print that indicates the bank that
the platform is booting from.

refactor(qemu): 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 QEMU platform only.

In order to isolate application memories, ELE FW introduces

So ELE configures SCM to access to external memory with CA35 DID
when CA35 request something from ELE.

Because ELE accesses DDR through NIC_LPAV, the XRDC MRC6 must be
configured for CA35 DID 7 to authorize the access.

feat(imx8ulp): update the upower config for power optimization

Enable the AFBB by default for active mode when APD side wakeup
from low power mode to align with the first time boot up.

Update the power mode configs to force shutdown all the
necessary power switches to optimize the power consumption.

To reduce the pad power consumption, put all the pad into
OFF mode to save more power. the PTD's compensation should
also be disabled in low power mode to save more power.

when APD enters PD mode, the LDO1(used by DDR) can be shutdown
to save power. when APD enters DPD mode, the BUCK3(supply for
APD/LPAV) can be shutdown to save power.

In single boot mode, When APD enters DPD mode, buck3 will
shutdown, LDO1 should be off to save more power as the DDR
controller has lost power.

In dualboot mode, the LPAV is owned by RTD side. When APD enters
low power mode, APD side should not config those PMIC regulators
that used by the resource owned by RTD side.
