This ioctl is used to signal the drivers that the screen is rotated, not to make the drivers rotate the screen.
- add a driver-specific "rotation_set" function
- implement Intel's rotation_set by setting the right values to the PIPECONF registers.
The idea is that when user-space does rotation, it can call this ioctl to inform the Kernel that we have a rotation. This feature is needed by the KVMr feature of VPro.

Quick comments before I dig into this: - Please post at least a link to the userspace patches, so that it's possible to check how this all fits together - Please separate the generic infrastructre in drm from the changes to support this in i915. I know, this is a rather small feature, but still.
