This contains the following changes:
* Overlay surface alpha is configured separately from the overlay. This
prevents display glitches (configure and fill the overlay first, set
alpha to a visible value next)
* Added an ioctl for configuring transparency of the Overlay and graphics
planes. Blend mode, colorkey mode and global alpha mode are supported.
* Added an ioctl for setting the plane order. The overlay plance can be placed
over or
under the graphics plane.
* Added an ioctl for setting and reading chip registers, with mask.
* Updated copyright for 2007

* Coding style changes

This patch adds a way to create and use the video plane (YUV overlay) and
scaling video scaling features of the chip.
The overlay is configured, resized and modified using a device specific
ioctl.
Also included in this patch:
- If no platform data was passed, print an error and exit instead of crashing.
- Added a write_reg(_dly) macro. This improves readability when
manipulating chip registers. (no more udelay() after each write).
- Comments about some issues.
