usb: dwc3: dwc3-omap: Disable/Enable only wrapper interrupts in prepa…

…re/complete

The dwc3 wrapper driver should not be fiddling with the core interrupts.
Disabling the core interrupts in prepare stops xhci from proper operation.
So remove disable/enable of core interrupts from prepare/complete.
