This module provides a driver for MDIO bus multiplexers that
are controlled via a simple memory-mapped device, like an FPGA.
The multiplexer connects one of several child MDIO busses to a
parent bus. Child bus selection is under the control of one of
the FPGA's registers.
Currently, only 8/16/32 bits registers are supported.
