drm: move drv test macros out of drmP.h 



Last bit the prevented us from starting to delete the drmP.h monster
includes from source files!

Also add kernel-doc while moving them.

A nice consistent drm_dev_ prefix would be cute for these, but since
they're used everywhere I've figured I'll leave this bikeshed aside
for now.
