[PATCH 10/10] arm: imx: imx8m: Add basic PSCI provider implementation

[sbabic at denx.de]

> Implement basic PSCI provider to let OS turn CPU cores off and on,
> power off and restart the system and determine PSCI version. This
> is sufficient to remove the need for the ATF BL31 blob altogether.
> To make use of this functionality, active the following Kconfig options:
>   # CONFIG_PSCI_RESET is not set
>   CONFIG_ARMV8_MULTIENTRY=y
>   CONFIG_ARMV8_SET_SMPEN=y
>   CONFIG_ARMV8_SPL_EXCEPTION_VECTORS=y
>   CONFIG_ARMV8_EA_EL3_FIRST=y
>   CONFIG_ARMV8_PSCI=y
>   CONFIG_ARMV8_PSCI_CPUS_PER_CLUSTER=4
>   CONFIG_ARMV8_SECURE_BASE=0x970000
>   CONFIG_ARM_SMCCC=y
>   CONFIG_SYS_HAS_ARMV8_SECURE_BASE=y
