usb_mux: Optimize reading mux state on unconnected port
If Type-C port has nothing connected then the query
of mux state should not power on the mux for reading
the state.
This helps reduce unnecessary power on/off retimer
or mux for ports with no device attached to it.
BUG=b:174240235
BRANCH=None
TEST=Test enumeration of type-c devices is not affected.
Also check on voxel if retimer init is not called periodically
when device is not connected.
