[PATCH v9 3/5] drm/panel: support for auo, kd101n80-45na wuxga dsi video mode panel

[Jitao Shi <jitao.shi@mediatek.com>]

Auo,kd101n80-45na's connector is same as boe,tv101wum-nl6.
The most codes can be reuse.
So auo,kd101n80-45na and boe,tv101wum-nl6 use one driver file.
Add the different parts in driver data.
