[PATCH 2/2] ARM: dts: imx6q: add quirky select input for USB_OTG_ID

For some reason, the select input of pin function USB_OTG_ID is not
implemented via a regular select input register but using the bit
USB_OTG_ID_ SEL (shift 13) of IOMUXC_GPR1 register (offset 0x4).

As per the workaround for such quirk implemented in pinctrl driver,
we need to compose the input_val cell as below.

	31     23      15      7        0
	| 0xff | shift | width | select |

Thus, we have 0xff0d0100 for MX6QDL_PAD_ENET_RX_ER__USB_OTG_ID and
0xff0d0101 for MX6QDL_PAD_GPIO_1__USB_OTG_ID in input_val cell.
