Subject: drm: Enable pr_debug() for drm_printer
Git-commit: 79a5ad2fdb3cb48e9c4e9d0d7688f0401cdb85d5
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

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.
