imx: add i.MX8 SoCs thermal alarm SIP(silicon provider) service support
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.
