    usb: gadget: pch_udc: Detecting VBUS through GPIO with interrupt
    
    Problem:
     pch_udc continues operation even if VBUS becomes Low.
     pch_udc performs D+ pulling up before VBUS becomes High.
     USB device should be controlled according to VBUS state.
    
    Root cause:
     The current pch_udc is not always monitoring VBUS.
    
    Solution:
     The change of VBUS is detected using an interrupt of GPIO.
     If VBUS became Low, pch_udc handles 'disconnect'.
     After VBUS became High, a pull improves D+, and pch_udc
     handles 'connect'.
