phy: rockchip-inno-usb2: disable id irq in pm suspend

The otg id voltage is provided from usb2 phy power. On some
rockchip platforms (e.g. rk3399), the usb2 phy power will be
turned off when enter pm suspend, this will trigger id fall
interrupt. But current code enable the ID interrupt consistently,
it may result in the mistake of ID changing operation even if
the state of ID pin is not changed. So disable ID irq when
suspend and enable when resume.
