Add 50ms disable delay for NV116WHM-N49, NV122WUM-N41, and MNC207QS1-1
to satisfy T9+T10 timing. Add 50ms disable delay for MNE007JA1-2
as well, since MNE007JA1-2 copies the timing of MNC207QS1-1.
Specifically, it should be noted that the MNE007JA1-2 panel was added
by someone who did not have the panel documentation, so they simply
copied the timing from the MNC207QS1-1 panel. Adding an extra 50 ms
of delay should be safe.
Fixes: 0547692ac146 ("drm/panel-edp: Add several generic edp panels")
Fixes: 50625eab3972 ("drm/edp-panel: Add panel used by T14s Gen6 Snapdragon")
