Separate the W90X900(W90P910) on-chip host controller driver from
ehci-hcd host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before W90X900(W90P910)
can be booted with a multi-platform kernel

and an ehci driver that only works on one of them.

With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the w90X900 bus glue.

V2:
 -Arranged  #include's in alphabetical order.
 -Replaced "w90p910" by "w90x900" because it is supports
  all series of w90x900.

+MODULE_DESCRIPTION(DRIVER_DESC);
 MODULE_AUTHOR("Wan ZongShun [off-list ref]");
-MODULE_DESCRIPTION("w90p910 usb ehci driver!");
-MODULE_LICENSE("GPL");
 MODULE_ALIAS("platform:w90p910-ehci");
+MODULE_LICENSE("GPL v2");

Are you sure the license is supposed to be changed?  Is that okay with 
Wan ZongShun?
