Mustafa Yigit Bilgen bd0c2f8d99 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_BL_RPMB_SERVICE: bootloader issues this SMC to sign or verify RPMB frames.
