Subject: [PATCH/RFC 5/6] arm64: dts: r8a7795: Fix non-PMIC wake-up sources

The PSCI firmware on boards equipped with an R-Car H3 SoC implements the
PSCI SYSTEM_SUSPEND operation by cutting power to the SoC.  Hence the
only possibly wake-up sources are the ones connected to the PMIC, unless
the "arm,psci-system-suspend-is-power-down" property is specified.
