To support TPM start method with SIP, SIP handler dispatch request to secure partition via MM_COMMUNICATE abi. That means spm_mm sip handler should generate mm communication header. Move mm_communication header's definition to spm_mm_svc header. Change-Id: I40567c16e67b068ee83a39eff050d6578aecfb2c Signed-off-by: Levi Yun <yeoreum.yun@arm.com>
