[PATCH] drm: kill more unused DRM macros

[Andres Salomon]

There are a few more macros in drmP.h that are unused; DRM_GET_PRIV_SAREA,
DRM_ARRAY_SIZE, and DRM_WAITCOUNT can go away completely.

Unfortunately, DRM_COPY is still used in one place, but we can at least
move it to where it's used.  It's an awful looking macro..
