fix(smccc): ensure that mpidr passed through SMC is valid

There are various SMC calls which pass mpidr as an argument which is
currently tested at random places in SMC call path.
To make the mpidr validation check consistent across SMC calls, do
this check as part of SMC argument validation.

This patch introduce a helper function is_valid_mpidr() to validate
mpidr and call it as part of validating SMC arguments at starting of
SMC handlers (which expect mpidr as an argument).

Additionally remove duplicate checks in SPMD similar checks are in

fix(sdei): ensure that interrupt ID is valid

As per SDEI spec (section 5.1.14.1), SDEI_INTERRUPT_BIND interface
expects a valid PPI or SPI. SGI's are not allowed to be bounded.
Current check in the code only checks for an SGI and returns invalid
ID. This check is insufficient as it will not catch architecturally
invalid interrupt IDs.

Modify the check to ensure that interrupt is either PPI or SPI.
