Add DRM_ROTATE_ and DRM_REFLECT_ defines to the UAPI as a convenience.

Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.

As a result these defines are provided purely as a convenience to
userspace applications.

drm_mode.h might be a better fit.

Comments look quite good, small question:
Is it plane only? Haven't looked at the code, but gut feeling says no.

The UAPI headers do not use BIT(). Please use (1<<x) instead.

About this, I don't disagree, but other defines in drm_mode.h seem to be 
prefixed with DRM_MODE_ which this isn't which is why I didn't put it there.

Knowing this, do you still prefer these defines living in drm_mode.h?

Feel free to give them a DRM_MODE_ prefix or something else - say
DRM_MODE_PROP_.

AFAICT drm_mode.h deals with KMS specifics and the prop_id mentioned
in the documentation is already there, so it would make sense to add
it there.
