MLK-20116-3 mx7ulp_evk: Remove GPIO codes for USB ID
The iMX7ULP B0 chip has added more pins for muxing USB ID. The A3 board
follows it to exploit PTC13 for USB ID, so we don't need to use GPIO
any longer. The USB driver can recognize the USB mode from USB PHY.
After this change, old boards with design using GPIO for USB mode won't
be supported.
