Moving the PCI-specific parts of the EHCI driver into their own file
created a few issues ... notably on resume paths which (like swsusp)
require re-initializing the controller.  This patch:

 - Splits the EHCI startup code into run-once HCD setup code and
   separate "init the hardware" reinit code.  (That reinit code is
   a superset of the "early usb handoff" code.)

 - Then it makes the PCI init code run both, and the resume code only
   run the reinit code.

 - It also removes needless pci wrappers around EHCI start/stop methods.

 - Removes a byteswap issue that would be seen on big-endian hardware.

The HCD glue still doesn't actually provide a good way to do all this
run-one init stuff in one place though.
