Consider that non-secure world may report TEE_ERROR_NOT_IMPLEMENTED
error code on OPTEE_RPC_CMD_RPMB_PROBE_RESET RPC command when that
RPC command is not supported. This is needed to support U-Boot
that provides this return code, at least up to its release tag
v2025.01 [1].
Without this change, OP-TEE fails to communicate with U-Boot RPMB
RPC service since RPMB probe capability was merged in OP-TEE
(Fixes: tag below).
