TCPMv2: Obtain correct dual role state when going suspend
Some boards (eg. eve) don't source VBUS in S3 state. In this case
DRP state should be set to force sink instead of toggle off.
This CL introduces pd_get_drp_state_in_suspend() function and
uses it to obtain correct DRP state when entering suspend.
Default implementation of pd_get_drp_state_in_suspend() returns
PD_DRP_TOGGLE_OFF, so this commit introduces no functional changes.
BUG=b:162254118
BRANCH=none
TEST=No functional changes in this CL
