Merge branch 'platform-data-controls-for-mdio-gpio'

Andrew Lunn says:

====================
platform data controls for mdio-gpio

Soon to be mainlined is an x86 platform with a Marvell switch, and a
bit-banging MDIO bus. In order to make this work, the phy_mask of the
MDIO bus needs to be set to prevent scanning for PHYs, and the
phy_ignore_ta_mask needs to be set because the switch has broken
turnaround.

Add a platform_data structure with these parameters.
