[ Upstream commit 1511d3c4d2bb30f784924a877f3cef518bb73077 ]
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.
