[Intel-gfx] [PATCH] drm/i915: Introduce i915_dbg macro

[akash.goel at intel.com]

From: Akash Goel <akash.goel at intel.com>

Added a new macro i915_dbg, which is a wrapper over dev_dbg macro.
dev_dbg allows use of dynamic debug framework, so offers a number
of advantages over DRM_DEBUG to debug user space startup issues.
Like provides more fine grain control by allowing to enable/disable
certain debug messages of interest on the fly, also allows filtering
of debug messages based on pid.
