refactor(armada): 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 Armada SoC of Marvell's platform.

fix(psci): mask the Last in Level nibble in StateId

In the ARM recommended StateID Encoding, the index for the power
level where the calling core is last to go idle use the last niblle
of the StateId.

Even if this nibble is necessary for OS-initiated mode, it can be
used by caller even when this OSI mode is not used.

In arm_validate_power_state() function, the StateId is compared with
content of arm_pm_idle_states[] build with the arm_make_pwrstate_lvl2
macro, without Last in Level information. So it is safe to mask this
nibble for ARM platform in all the cases, and that avoids issues with
caller with use the same StateId encoding with OSI mode activated or
not (in tftf tests for example, the input(power state) parameter =
(0x40001022) and the associated power state is 0x40000022).

refactor(smccc): refactor vendor-el3 build

Currently we are building vendor-specific EL3 by default similar to
arm-sip but unfortunately this causes few troubles for now.

- Few model builds configuration like 'fvp-dynamiq-aarch64-only'
is on 256KB SRAM border and this configuration is also run on some
older models like A710 and N2, so we cant move them to 384KB SRAM size
and to new model.

- Not able to move some older model builds to new model due to known
issue in power modelling in some of the models, making it difficult to
transition.

However vendor-specific EL3 is currently using PMF, DEBUGFS so building
the vendor EL3 support only when any of this sub-service is built also
helps to avoid bloating BL31 image size in certain configurations.

However this is not end of road, we will monitor how vendor-specific EL3
grows with sub-service and if needed will make this interface to built
by default like arm-sip range. Also this doesn't stop platform owners to
make vendor-specific EL3 to be enabled by default for their platform
configuration.
