USB: EHCI: make ehci-msm a separate driver
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 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 msm bus glue.
In V5 (arnd):
- add FIXME about missing usb_add_hcd() or usb_remove_hcd() calls
In V3:
- 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
structure initialization instead of "msm-ehci", which was the reason
why it broke in EHCI USB testing
In V2:
Tegra patch related changes removed from this patch.
