[PATCH] drm/panel: Fix boe,tv101wum-n53 htotal timing

The datasheet suggests 60 for tHFP, so let's adjust the number
accordingly.

This also makes the framerate be 60Hz as intended:
159916.0 * 1000 / ((1200 + 80 + 24 + 60)*(1920 + 20 + 4 + 10))
=> 60.00 Hz

This also matches the values that we use in our chromeos-4.19
vendor kernel.

Applies on top or drm-misc/drm-misc-next.
