Subject: [PATCH 4/6] xen-platform: Convert to generic power management

From: Bjorn Helgaas <bhelgaas@...gle.com>

Convert xen-platform from the legacy PCI power management callbacks to the
generic operations.  This is one step towards removing support for the
legacy PCI callbacks.

The generic .resume_noirq() operation is called by pci_pm_resume_noirq() at
the same point the legacy PCI .resume_early() callback was, so this patch
should not change the xen-platform behavior.
