Just like the OHCI counter part we just can remove the architecture

Separate the  Qualcomm QSD/MSM 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 Qualcomm QSD/MSM
can be booted with a multi-platform kernel, which is not expected before
3.11.

With the infrastructure added by Alan Stern in patch 3e023203
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate

 - Detailed commit message added here describing why this patch is required.
 - Arranged  #include's in alphabetical order.
 - driver.name initialized hcd_name[] = "ehci-msm" in platform_driver

   why it broke in EHCI USB testing

With the multiplatform changes in arm-soc tree, it becomes
possible to enable the mvebu platform (which uses
