mb/intel/jslrvp: Update SLP_Sx assertion widths and PwrCycDur
This patch updates the SLP_Sx assertion widths and power cycle duration
for the Japerlake RVP.
Power cycle duration:
With default value,
S0->S5 -> [ ~4.2 seconds delay ] -> S5->S0
With value set to 1,
S0->S5 -> [ ~1.2 seconds delay ] -> S5->S0
BUG=b:159104150
TEST=Verified that the power cycle duration is ~1.2s with global
reset on JSLRVP.
