This patch reorganizes the startup and shutdown code in the dummy-hcd
driver to make it consistent with all the other host controller drivers.
For example, the platform device representing the HC hardware is
allocated separately and given as an argument to the probe() and remove()
routines, as it would be for a real device.

This paves the way to making widespread and uniform changes in all the
HCDs at once.  Please apply.
