CHERRY-PICK: pd_protocol: Only suspend task when TCPC enters LPM.
This commit fixes an issue of "suspending" the PD tasks prior to
actually entering low power mode. Really, the only place to suspend the
tasks should be where we put the TCPCs into low power mode.
BUG=b:119501850
BRANCH=firmware-nocturne-10984.B,master
TEST=flash nocturne; suspend DUT, resume DUT, verify that TCPCs enter
low power mode after a short time of being in PD_STATE_DRP_AUTO_TOGGLE.
