Commit@f7679d437d5f27a3168f017db8d42bc561ac0c59 PMF is moved under vendor specific EL3 range, part of this we have introduced each sub-service have an version scheme[1]. - Current PMF is not handling correctly identifying all FID's under it so handle this correctly. - Minor refactor to use existing macro GET_SMC_NUM rather than manual parsing to find the SMC number.
