platform/chrome: cros_ec_typec: Set opmode to PD on SOP connected

Browse Source 
When SOP Discovery is done, set the opmode to PD if status indicates
SOP is connected.

SOP connected indicates a PD contract is in place, and is a solid
indication we have transitioned to PD power negotiation, either as
source or sink.
