ARM: davinci: da850-evm: use GPIO hogs instead of the legacy API
In order to drop the hard-coded GPIO base values from the davinci GPIO driver's platform data, we first need to get rid of all calls to the legacy GPIO functions. Convert the mdio configuration to hogging the relevant GPIO line in the da850-evm board file.
