Manish Pandey 96546b5cc3 feat(smccc): introduce TPM Start SMC ...

To support TPM start method compatible with pre-FFA configuration (to
support SPM_MM) introduce an SMC FID el3 vendor specific range. This
SMC is forwarded to SPM_MM module which converts into a MM_COMMUNICATE
to interact with Secure partition.

TPM Start method is mentioned in TCG ACPI spec section 3.3.1
https://trustedcomputinggroup.org/wp-content/uploads/TCG-ACPI-Specification-Version-1.4-Revision-15_pub.pdf

As this patch introduces a new sub service, increment minor version
of Vendor EL3 service.
