net: mdio_bus: Use devm for getting reset GPIO

Browse Source 
Commit bafbdd527d ("phylib: Add device reset GPIO support") removed
devm_gpiod_get_optional() in favor of the non-devres managed
fwnode_get_named_gpiod(). When it was kind-of reverted by commit
40ba6a12a5 ("net: mdio: switch to using gpiod_get_optional()"), the devm
functionality was not reinstated. Nor was the GPIO unclaimed on device
remove. This leads to the GPIO being claimed indefinitely, even when the
device and/or the driver gets removed.

Fixes: bafbdd527d ("phylib: Add device reset GPIO support")
Fixes: 40ba6a12a5 ("net: mdio: switch to using gpiod_get_optional()")
