USB: Fix suspend-resume of PCI USB controllers
Commit a0d4922da2e4ccb0973095d8d29f36f6b1b5f703
(USB: fix up suspend and resume for PCI host controllers) attempted
to fix the suspend-resume of PCI USB controllers, but unfortunately
it did that incorrectly and interrupts are left enabled by the USB
controllers' ->suspend_late() callback as a result. This leads to
serious problems during suspend which are very difficult to debug.
Fix the issue by removing the ->suspend_late() callback of PCI
USB controllers and moving the code from there to the ->suspend()
callback executed with interrupts enabled. Additionally, make
the ->resume() callback of PCI USB controllers execute
pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the
full power state (PCI_D0).
