USB: quirks: Add USB_QUIRK_DISCONNECT_SUSPEND quirk for
Lenovo A630Z TIO built-in usb-audio card

Add a USB_QUIRK_DISCONNECT_SUSPEND quirk for the Lenovo TIO built-in
usb-audio. when A630Z going into S3,the system immediately wakeup 7-8
seconds later by usb-audio disconnect interrupt to avoids the issue.

Seeking a better fix, we've tried a lot of things, including:
 - Check that the device's power/wakeup is disabled
 - Check that remote wakeup is off at the USB level
 - All the quirks in drivers/usb/core/quirks.c
   e.g. USB_QUIRK_RESET_RESUME,
        USB_QUIRK_RESET,
        USB_QUIRK_IGNORE_REMOTE_WAKEUP,
        USB_QUIRK_NO_LPM.

but none of that makes any difference.

There are no errors in the logs showing any suspend/resume-related issues.
When the system wakes up due to the modem, log-wise it appears to be a
normal resume.

Introduce a quirk to disable the port during suspend when the modem is
detected.
