fix: mvebu_ comphy: Update COMPHY sequence number

Browse Source 
Use local static counter for maintaining the COMPHY chip-ID
upon its initialization.
The dev->seq originally used as the COMPHY chip-ID depends
on the device tree scan order and produces wrong results
that breaks the deficated PHYs init flow, which in turn
breaks the USB support.
