Subject: [PATCH v2 11/12] arm64: dts: qcom: sa8775p: Clean up the PSCI PDs

From: Konrad Dybcio <konrad.dybcio@....qualcomm.com>

Because SA8775P comes with two disjoint CPU clusters, we have to follow
a similar topology description like the one in sm8750.dtsi, so:

system_pd
	cluster0_pd
		cpu_pd0
		...
	cluster1_pd
		cpu_pd4
		...

Do that & wire it up to APPS RSC to make the bindings checker happy.
