mdio-gpio: Add reset functionality to mdio-gpio driver(v2).
This patch adds phy reset functionality to mdio-gpio driver. Now mdio_gpio_platform_data has new member as function pointer which can be filled at the bsp level for a callback from phy infrastructure. Also the mdio-bitbang driver fills-in the reset function of mii_bus structure. Without this patch the bsp level code has to takecare of the reseting PHY's on the bus, which become bit hacky for every bsp and phy-infrastructure is ignored aswell.
