[Intel-gfx] [PATCH 04/18] drm/i915/display/display: Prefer drm_WARN_ON over WARN_ON

[Pankaj Bharadiya]

struct drm_device specific drm_WARN* macros include device information
in the backtrace, so we know what device the warnings originate from.

Prefer drm_WARN_ON over WARN_ON at places where struct drm_device
pointer can be extracted.
