usb: gadget: pch_udc: Reduce redundant interrupt
commit 833310402c54ad9b676b465fc53ad276b13d36be upstream.
ISSUE:
USB Suspend interrupts occur frequently.
CAUSE:
When it is called pch_udc_reconnect() in USB Suspend, it repeats reset and
Suspend.
SOLUTION:
pch_udc_reconnect() does not enable all interrupts. When an enumeration event
occurred the driver enables all interrupts.
