ARM: i.MX: edmqmx6: free phy-reset gpio pin
Since 93a6c6a808("dts: update to v3.17-rc2") we have a correct gpio
configuration. This results in a double gpio request what receipted in a
error message like this one:
gpiolib: _gpio_request: gpio-25 (phy-reset) status -16
Now with this patch the problem is gone.
