drm: Add drm_puts() to complement drm_printf()
Add drm_puts() for a much faster path to print constant strings into a drm_printer object with memcpy and friends. This can have seconds off of really large outputs such as GPU dumps. If the drm_printer object supports a custom puts function then use that otherwise fall back to the slower legacy printf call. v2: Add documentation for drm_puts() per Daniel Vetter Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> [robclark fix minor htmldocs warning] Signed-off-by: Rob Clark <robdclark@gmail.com>
