mb/google/kahlee: Set stapm parameters with time value fixed
stapm_time passed to smu via agesa is in msec. With earlier value
smu was getting stapm_time as 2.5 sec instead of 2500 sec and thus
causing issue in S3, and audio in PsppBalanceLow state.
BUG=b:117569918, b:117252463
TEST=
1.) audio works with PsppBalanceLow
2.) S3 cycles
