This patch (as1563) removes a lot of duplicated code by moving the
EHCI controller suspend/resume routines into the core driver, where
the various platform drivers can invoke them as needed.
Not only does this simplify these platform drivers, this also makes it
easier for other platform drivers to add suspend/resume support in the
future.
Note: The patch does not touch the ehci-fsl.c file, because its
approach to suspend and resume is so different from all the others.
It will have to be handled specially by its maintainer.

The update_device callback is not needed and the function used here is
from the pci ehci driver. Without this patch we get a compile error if
ehci-platform is compiled without ehci-pci.

This adds a generic driver for platform devices. It works like the PCI
driver and is based on it. This is for devices which do not have an own
bus but their EHCI controller works like a PCI controller. It will be
used for the Broadcom bcma and ssb USB EHCI controller.
