drm/i915/display/ddi: Make WARN* drm specific where drm_device ptr is available
drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.
Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.
The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.
