drm/panel: simple: Add Innolux G121XCE-L01 LVDS display support

G121XCE-L01 is a Color Active Matrix Liquid Crystal Display composed of
a TFT LCD panel, a driver circuit, and LED backlight system. The screen
format is intended to support the 4:3, 1024(H) x 768(V) screen and either
262k/16.7M colors (RGB 6-bits or 8-bits) with LED backlight driver circuit.
All input signals are LVDS interface compatible.

Documentation [1] and [2] indicate that G121X1-L03 and G121XCE-L01 are
effectively identical panels, use the former as RGB 6-bits variant and
add the later as RGB 8-bits variant.
