On i.MX8QM/i.MX8QX with system controller inside, the SRTC is managed by SCFW(system controller firmware) and some functions like setting SRTC's time etc. can ONLY be requested from secure world, so SIP runtime service is needed for such kind of operations, this patch adds SRTC SIP runtime service support for i.MX8QM and i.MX8QX.
