[RESEND PATCH 1/2] drm/panel: Add support for Armadeus ST0700 Adapt

[Sébastien Szymanski]

This patch adds support for the Armadeus ST0700 Adapt. It comes with a
Santek ST0700I5Y-RBSLW 7.0" WVGA (800x480) TFT and an adapter board so
that it can be connected on the TFT header of Armadeus Dev boards.
