Subject: [PATCH] drm/panel: Update Boe-tv110c9m initial code

Optimize two problems

a)Turn off low voltage detection register.During the esd test,
the low-voltage detection ic may be triggered to enter the slpin state,
so a black screen occurs on the panel.
b)Optimize CMD2 page1 gamma.

While continuing to grumble about not liking this big binary command
stream, I'll still apply it since we've accepted the previous ones. At
some point I'm going to get fed up with it, though, and say that this
needs to be converted to something understandable instead of a big
pile of binary data.
