Subject: [media] rename drivers/media/video as .../platform

The remaining drivers are mostly platform drivers. Name the
dir to reflect it.

It makes sense to latter break it into a few other dirs.

- *				to the virtual space of desired rotation angle
- * 4-DEC-2006  Jian		Changed to support better memory management
- *
- * 17-Nov-2008 Hardik		Changed driver to use video_ioctl2
- *
- * 23-Feb-2010 Vaibhav H	Modified to use new DSS2 interface
