For NXP's i.MX8 SoCs with system controller inside, thermal sensors are maintained by SCFW, Linux needs to call SMC to trap to TF-A for thermal alarm operation etc. by calling SCFW API. This patch adds temperature alarm SIP service support. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

On i.MX8QM/i.MX8QX with system controller inside, the wakeup source is managed in SCFW(system controller firmware), if the wakeup source is belonged to system controller partition, then before Linux suspend, the wakeup source should be set to SC_PM_WAKE_SRC_SCU, and if the wakeup source is belonged to Cortex-A partition, the wakeup source should be set to SC_PM_WAKE_SRC_IRQSTEER, so need to add wakeup source SIP runtime service to get Linux kernel's wakeup source and set the correct wakeup source for system controller.

On i.MX8QM/i.MX8QX with system controller inside, the CPU's clock rate is managed by SCFW(system controller firmware) and can ONLY be changed from secure world, so SIP runtime service is needed for setting CPU's clock rate, this patch adds cpu-freq SIP runtime service support.

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.
