[PATCH 3/7] imx: ventana: remove phy gpio reset from dt

[Tim Harvey]

We configure network phy configuration for internal delay, LED config,
and clock config. If we leave the phy reset gpio defined in dt the
kernel may issue a reset to the phy and break these configs. While some
may be handled by a kernel phy driver, others may not (typically LED
config).
