arm64: dts: r8a7795: Upgrade to PSCI v1.0 to support Suspend-to-RAM
>From PSCI v1.0, Suspend-to-RAM is supported via SYSTEM_SUSPEND PSCI
function call. Hence, upgrade PSCI version for R-Car H3 to support
Suspend-to-RAM.
The Suspend-to-RAM is highly dependent on ARM Trusted Firwmare support
since necessary callback functions will be registered after a query
to ARM Trusted Firmware about SYSTEM_SUSPEND support.
Since PSCI v1.0 is backward compatible with PSCI v0.2, CPU Hotplug and
CPUIdle should be able to work normally with this change.
