drivers: net: driver for MDIO muxes controlled over I2C

Browse Source 
This driver is used for MDIO muxes driven over I2C.  This is currently
used on Freescale LS1028A QDS board, on which the physical MDIO MUX is
controlled by an on-board FPGA which in turn is configured through I2C.

This driver is used for MDIO muxes driven by writing to a register of
an I2C chip. The board it was developed for uses a mux controlled by
on-board FPGA which in turn is accessed as a chip over I2C.
