lm4: Fixed low power idle doesn't always wake up.stabilize-4920.6.Brelease-R32-4920.B
Temporary fix to the bug in which we miss wake events when in deep
sleep with the LFIOSC (32kHz) clock and the EC is cold. This fix
involves simply using a faster clock, 250kHz, when in low speed
deep sleep. This fix consumes more power but solves the bug.
Renamed EC console command dsleepmask to dsleep.
BRANCH=none
BUG=chrome-os-partner:23678
TEST=Go in to low speed deep sleep by going into either S3 or G3
and letting the EC console timeout. Then freeze-spray the EC chip.
Wake up the EC via the console and make sure that the idlestats
show that we have not missed a deadline.
