Subject: drm/panel: Fix boe,tv101wum-n53 htotal timing
Git-commit: c6cccafa9191f087154f44b94987076617244227
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
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
