the default mode of GPIO16 pin is gpio, when set EINT16 to
IRQ_TYPE_LEVEL_HIGH, no interrupt is triggered, it can be
fixed when set its default mode as usb iddig.

Chunfeng, GPIO16 can be used as EINT16 mode, but the pinmux should be 0.
If you want to set its default mode to iddig, you should set it in dts.
