drm: Rename drm_utils.h to drm_panel_quirks.h

Now that the timeout-related functions were removed from drm_utils.h,
the header has exclusively panel orientation and backlight quirk getters.

Therefore, rename the header accordingly and update all files that
include it. The files amdgpu_dm.c, amdgpu_dm_connector.c and panthor_drv.c
include the header but don't use it, so drop the include there.

No functional change.
