Alan Stern a0d4922da2 USB: fix up suspend and resume for PCI host controllers 
This patch (as1192) rearranges the USB PCI host controller suspend and
resume and resume routines:

	Use pci_wake_from_d3() for enabling and disabling wakeup,
	instead of pci_enable_wake().

	Carry out the actual state change while interrupts are
	disabled.

	Change the order of the preparations to agree with the
	general recommendation for PCI devices, instead of
	messing around with the wakeup settings while the device
	is in D3.

		In .suspend:
			Call the underlying driver to disable IRQ
				generation;
			pci_wake_from_d3(device_may_wakeup());
			pci_disable_device();

		In .suspend_late:
			pci_save_state();
			pci_set_power_state(D3hot);
			(for PPC_PMAC) Disable ASIC clocks

		In .resume_early:
			(for PPC_PMAC) Enable ASIC clocks
			pci_set_power_state(D0);
			pci_restore_state();

		In .resume:
			pci_enable_device();
			pci_set_master();
			pci_wake_from_d3(0);
			Call the underlying driver to reenable IRQ
				generation

	Add the necessary .suspend_late and .resume_early method
	pointers to the PCI host controller drivers.
