[PATCH] drm: Enable pr_debug() for drm_printer

[Chris Wilson]

pr_debug() is conditionally compiled and requires either
dynamic-debugging to be enabled or for the code to opt-in using #define
DEBUG. Since drm_print provides a central debugging facility using
pr_debug(), make sure it will always produce output.
