arm64: dts: qcom: sc7180: Add specific APPS RSC compatible

SC7180 comes in a couple firmware flavors, some of which don't support
PSCI in OSI mode. That prevents the power domain exepcted by the RSC
node from providing useful information on system power collapse.

Use the platform-specific compatible to allow not passing one.
