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.
