[PATCH 2/2] drm/panel: simple: Add support for Innolux LS075AT011

[Lubomir Rintel <lkundrak@v3.sk>]

This adds support for the Innolux LS075AT011 7.5" 1200x900 panel. There's
no public data sheet for the panel -- the values have been taken from Open
Firmware and the documentation for the display controller that drives
the panel and tested on the OLPC laptop.
