retimer: PD port retimer firmware update support
Added one field to struct usb_mux_driver, which returns true if
retimer update is supported.
Moved query function from usb_retimer_fw_update.c to usb_mux.c.
BUG=b:162528867
BRANCH=none
TEST=Tested on Voxel, together with related coreboot and kernel changes.
EC returns correct port information to kernel.
