Arun Parameswaran 6f08e98d62 net: phy: restore mdio regs in the iproc mdio driver
The mii management register in iproc mdio block
does not have a retention register so it is lost on suspend.
Save and restore value of register while resuming from suspend.

Yendapally Reddy Dhananjaya Reddy bb1a619735 net: phy: Initialize mdio clock at probe function
USB PHYs need the MDIO clock divisor enabled earlier to work.
Initialize mdio clock divisor in probe function. The ext bus
bit available in the same register will be used by mdio mux
to enable external mdio.
