Revert "usb: dwc3: dwc3-omap: Disable/Enable only wrapper interrupts in prepare/complete"
This reverts commit 02dae36aa649a66c5c6181157ddd806e7b4913fc.
That commit is bogus in two ways:
1) There's no way dwc3-omap's ->suspend() can cause any effect
on xhci's ->suspend(). Linux device driver model guarantees
that a parent's ->suspend() will only be called after all
children are suspended. dwc3-omap is the parent of the
parent of xhci.
2) When implementing Deep Sleep states where context is lost,
USBOTGSS_IRQ0 register, well, looses context so we
_must_ rewrite it otherwise core IRQs will never be
reenabled and USB will appear to be dead.
Fixes: 02dae36 (usb: dwc3: dwc3-omap: Disable/Enable only
wrapper interrupts in prepare/complete)
