[PATCH 5/6] imx8m: soc: drop phy-reset-gpios for fec

["Peng Fan (OSS)" <peng.fan@oss.nxp.com>]

From: Peng Fan <peng.fan@nxp.com>

Need to drop phy-reset-gpios before booting linux, this property
is legacy property and replaced with reset-gpios.

If provide both, kernel would failed to request the same gpio twice
and cause fec not work.
