Subject: drm/panel: simple: Check against num_timings when setting preferred for timing

From: Chen-Yu Tsai <wens@csie.org>

commit 230c5b44233ff0543c0b5ccf4ff9400057010fbe upstream.

In the loop on .timings, we should check .num_timings to see if it's the
only mode specified, not .num_modes, which should be used with .modes.
