mdio_bus: use devm_gpiod_get_optional()
The MDIO reset GPIO is really a classical optional GPIO property case, so devm_gpiod_get_optional() should have been used, not devm_gpiod_get(). Doing this saves several LoCs... Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: David S. Miller <davem@davemloft.net>
