refactor(allwinner): 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 only affects the Allwinner platform.

refactor(arm): console runtime switch on bl31 exit

Any BL31 setup and Runtime initialization within BL31 is still part of
the BOOT process. As such, the console flush and switch must be the
last calls before BL31 exit. Flush the console print buffer before
switching to runtime. This is so that there is no lingering chars in
the print buffer when we move to the runtime console.

This patch adds console flush before switching to runtime in
bl31_plat_runtime_setup() function (before BL31 exits). The plan is to
move flush and switch calls to bl31_main before BL31 exits, until then
console_flush() in bl31_main.c has been left as is.

This patch affects the Arm platform only.

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.

The version 2 of the FWU metadata structure has a field bank_state in

State. This is different from the binary states of Valid/Accepted
States that the bank could be in, as defined in the earlier version of
the specification.

Replace the fwu_is_trial_run_state() API with
fwu_get_active_bank_state() to get the state the current active bank
is in. The value returned by this API is then used by the caller to
take appropriate action.
