fix: replace platform get core pos usage
It is incorrect for secure partitions to use the platform_get_core_pos
macro. MPIDR_EL1 read from S-EL1 is the impdef virtual MPIDR value set
by the SPMC on behalf of SP. The MPIDR value does not hold physical CPU
affinity values, but the linear vCPU index for the currently running
vCPU. Add an SPM helper to retrieve the vCPU index information and
update call sites to use this helper.
