arm64: dts: qcom: sc7280: Update domain-idle-states for cluster sleep
QCM6490 uses Trustzone as firmware whereas SC7280 uses arm trusted firmware.
The PSCI suspend param and the number of domain-idle-states supported is
different in Trustzone for cluster sleep.
Move the arm trusted firmware supported domain-idle-states in chrome specific
sc7280-chrome-common.dtsi and add the Trustzone supported sleep states as default
domain-idle-states in sc7280.dtsi
