arm64: dts: qcom: sm6350: Add PSCI idle states
Add the PSCI idle states so that the CPU (among other things) can reach lower power states. Signed-off-by: Konrad Dybcio <konrad.dybcio@linaro.org> Signed-off-by: Bjorn Andersson <andersson@kernel.org> Link: https://lore.kernel.org/r/20230531-topic-rsc-v1-2-b4a985f57b8b@linaro.org
