imx: ventana: remove phy gpio reset from dt

Browse Source 
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).
