This patch series "brings to life" the hsotg driver. Before this patch
set it was supposed to work only with S3C64xx Samsung SoC.
Those (now) 15 commits shall be treated as a single patch series, and
we have agreed before Easter, that it is suitable for USB for-next.
Moreover I'm trying to upgrade this driver to the Kernel newest API
(udc_{start|stop}, regulators, platform independent code and now
clocks). Due to that I think that for-next is the best option - more
time for debugging and driver validation.
