[PATCH] net: stmmac: fix reset gpio free missing

[Jisheng Zhang]

Commit 984203ceff27 ("net: stmmac: mdio: remove reset gpio free")
removed the reset gpio free, when the driver is unbinded or rmmod,
we miss the gpio free.

This patch uses managed API to request the reset gpio, so that the
gpio could be freed properly.
