plat: imx8m: Implement IMX_SIP_BUILDINFO ...

The IMX_SIP_BUILDINFO call was implemented for imx8qm and imx8qx but
it's also applicable to imx8m.

This fixes U-Boot not printing commit hash on 8m with upstream TF-A.

imx: add i.MX8 SoCs build info SIP(silicon provider) service support ...

This patch adds NXP i.MX8 SoCs' build info SIP support for easy debug.
With this function enabled, TF-A's commit hash can be showed in u-boot
debug console when booting up, when there is any issue which could be
related to TF-A, users can use the commit hash value to easily identify
which commit introduces the issue.

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.

imx: add wakeup source SIP runtime service support ...

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.

imx: add cpu-freq SIP runtime service support ...

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.

imx: add imx8qm/imx8qx SRTC 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.
