Adds support for SPMD with SPMC at S-EL1. A new config option SPMC_OPTEE is added to support loading the special OP-TEE images when configured with SPD=spmd. With or without SPMC_OPTEE. It should still be possible to load another BL32 payload implementing a SPMC, provided that entry point is the same as load address, that is, BL32_BASE.
