[PATCH/RFC 6/6] arm64: dts: r8a7796: Fix non-PMIC wake-up sources

[Geert Uytterhoeven]

The PSCI firmware on boards equipped with an R-Car M3-W 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.
