Add SMCCC function IDs for RPMB read/write service on 32bit architectures.
Define generic SP_SVC_RPMB_READ/SP_SVC_RPMB_WRITE IDs for native target
architecture (32b or 64b).
Changes OpTeeRpmbFvb.c to use architecture agnostic macro
ARM_SVC_ID_FFA_MSG_SEND_DIRECT_REQ for 32b and 64b support.

Changes since v1:
- Use _AARCH64 (resp. _AARCH32) suffix instead of _64 (resp. _32) in
the added macros.
