arm64: dts: qcom: sm8550: Update idle state time requirements

Browse Source 
The idle state entry/exit/residency times differ from what shipped on
production devices, mostly being overly optimistic in entry times and
overly pessimistic in minimal residency times. Align them with
downstream sources.
