[src/trunk]: src/sys/external/bsd/drm2/drm Rename drm_drv.c to drm_cdevsw.c.

description:
Rename drm_drv.c to drm_cdevsw.c.
Previously we overrode upstream's drm_drv.c altogether, and used
upstream's drm_stub.c subroutines.
But upstream deleted drm_drv.c and renamed drm_stub.c to drm_drv.c,
so we have to cope with that reshuffle.
