PATCH v2 1/1 USB: OHCI: make ohci-da8xx a separate driver
From: Manjunath Goudar <[email protected]>
Separate the Davinci OHCI host controller driver from ohci-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

This was a previews patch submited by Manjunath [1] that was never taken in because of an undefined symbol when loading as a module. That symbol is not present anymore so we can safly build the driver as a module.
I rebased, fixing the minor remaining comments.
V1->V2
* changed hdc_name to a #define and use it in MODE_ALIAS (David)
* Added tested-by tag from David
