spd: tlkd: support new TLK SMCs for RPMB service
This patch adds support to handle following TLK SMCs:
{TLK_SET_BL_VERSION, TLK_LOCK_BL_INTERFACE, TLK_BL_RPMB_SERVICE}
These SMCs need to be supported in ATF in order to forward them to
TLK. Otherwise, these functionalities won't work.
Brief:
TLK_SET_BL_VERSION: This SMC is issued by the bootloader to supply its
version to TLK. TLK can use this to prevent rollback attacks.
TLK_LOCK_BL_INTERFACE: This SMC is issued by bootloader before handing off
execution to the OS. This allows preventing sensitive SMCs being used
by the OS.
TLK_BL_RPMB_SERVICE: bootloader issues this SMC to sign or verify RPMB
frames.
Tested by: Tests TLK can receive the new SMCs issued by bootloader
