Haneen Mohammed Oct. 17, 2017, 8:43 a.m. UTC 
This patch extract DRM_* debug macros from drmP.h to drm_print.h and
move printing related functions used by these macros from drm_drv.[hc]
to drm_print.[hc].

Signed-off-by: Haneen Mohammed <hamohammed.sa@gmail.com>
---
Changes in v3:
- Move debug macros and print functions into drm_print.[hc] instead of
introducing drm_debug.[hc].
