Subject: [PATCH v1 1/2] drm/panel: simple: add Multi-Innotechnology MI1010AIT-1CP1

From: Sam Ravnborg <sam@...nborg.org>

The Multi Innotechnology is a 10.1" 1280x800 panel.

The datasheet did not specify specific values for sync, back, front porch.
The values are a best guess based on values for similar panels.
