[PATCH v5 2/3] sta2x11_vip: convert to videobuf2 and control framework

[Dan Carpenter]

This would be easier to review if it were broken up into separate
patches.

1) There are superflous white spaces changes
2) Changes to the copyright
3) pr_warning => pr_warn
4) The REG_READ and REG_WRITE macros are now inline functions
5) KBUILD_MODNAME is used instead of DRV_NAME
6) It now uses the video_drvdata() function
7) Lots of comments deleted.  For exmple, vidioc_enum_fmt_vid_cap()
   didn't change.  Just the comments were deleted.
8) Comments added for existing code.
9) Other behavior changes not related to using videobuf2 like in
   vidioc_try_fmt_vid_cap().
10) etc...

If all the uninteresting changes are in separate patches it makes
the complicated stuff much shorter and easier to review.
