Niklas Neronin ff9a09b3e0 usb: xhci: fix host not responding after suspend and resume 
Partially revert commit e1db856bd2 ("usb: xhci: remove '0' write to
write-1-to-clear register") because the patch cleared the Interrupt Pending
bit during interrupt enabling and disabling. The Interrupt Pending bit
should only be cleared when the driver has handled the interrupt.

Ideally, all interrupts should be handled before disabling the interrupt;
consequently, no interrupt should be pending when enabling the interrupt.
For this reason, keep the debug message informing if an interrupt is still
pending when an interrupt is disabled.

Because the Interrupt Pending bit is write-1-to-clear, writing '0' to it
ensures that the state does not change.
