[PATCH v3 0/2] drm: Move debug macros out of drmP.h

[Haneen Mohammed]

This patchset move debug macros from drmP.h to drm_print.h and move
printing related functions used by the debug macros from drm_drv.[hc]
to drm_print.[hc].
In addition, it fixes old comment style.

Changes in v3:
- Move debug macros and print functions into drm_print.[hc] instead of
introducing drm_debug.[hc].
