usb: dwc3: dwc3-omap: Disable/Enable only wrapper interrupts in prepare/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. Signed-off-by: George Cherian <george.cherian@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
