mb/google/hatch: Set Reset Power Cycle Duration for hatch platforms
Currently, Reset Power Cycle Duration is set with default value (4s). This adds around ~5 seconds of delay during power cycle or global reset. So, this patch sets PchPmPwrCycDur (Reset Power Cycle Duration) to 1s to minimize the delay. Delay with Power Cycle or Global Reset: Existing behaviour: S0->S5 -> [ ~5 seconds delay ] -> S5->S0 With the patch: S0->S5 -> [ ~2 seconds delay ] -> S5->S0 Also, correct the comment mentioned for PchPmSlpAMinAssert. The value(3) defined for PchPmSlpAMinAssert triggers signal assertion width to 98ms not 2s.
