Subject: [PATCH -next v2] usb: dwc3: include extcon.h to fix compile error

If dwc3 is not include extcon.h, the dwc3 driver
will fail to link:

drivers/usb/dwc3/core.o: In function `dwc3_probe':
core.c:(.text+0x1095): undefined reference to `extcon_get_edev_by_phandle'
core.c:(.text+0x10bd): undefined reference to `extcon_get_extcon_dev'

Add miss #include <linux/extcon.h> to fix this error.

Fixes: 0f0101719138 ("usb: dwc3: Don't switch OTG -> peripheral if extcon is present")
