[PATCH 1/9] drm: Add drm_mode_debug_printmodeline_raw

[Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxxxxxxx>]

From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>

Purpose is to enable drivers to print out just the mode
string with their own formatting.

Existing drm_mode_debug_printmodeline calls the new
helper and the format is unchanged in this patch.
