mb/google/brask: Update PCH power cycle related durations
The power rails discharge time of brask has been measured, the longest discharge time of the power rails are smaller than 150ms so it is safe to set the pwr_cyc_dur to 1 second. Since the brask is derived from the brya, we could apply the same setting from the brya. The setting is copied from commit dee834aa. BUG=b:214454454 BRANCH=firmware-brya-14505.B TEST=`test_that firmware_ECPowerButton` passed.
