smb-lib: Handle icl voter priorities between DCP, SDP and PD type

Cleanup the code such that when PD is activated, DCP_VOTER
and USB_PSY_VOTER (the voter for SDP and CDP types) are disabled.

While at it DCP_VOTER is intended to enforce a different value
from the hw defaults. Set it only when type is confirmed DCP.

Also to handle the situation when the PD profile allows to suspend
based on the phy, use a different voter PD_SUSPEND_SUPPORTED_VOTER
to activate that situation.
