net: stmmac: use GPIO descriptors in stmmac_mdio_reset
Switch stmmac_mdio_reset to use GPIO descriptors. GPIO core handles the "snps,reset-gpio" for GPIO descriptors so we don't need to take care of it inside the driver anymore. The advantage of this is that we now preserve the GPIO flags which are passed via devicetree. This is required on some newer Amlogic boards which use an Open Drain pin for the reset GPIO. This pin can only output a LOW signal or switch to input mode but it cannot output a HIGH signal. There are already devicetree bindings for these special cases and GPIO core already takes care of them but only if we use GPIO descriptors instead of GPIO numbers.
