  Add BOE EV121WXM-N10-1850 12.1" WXGA (1280x800) TFT LCD panel support.
The panel has a LVDS display interface.

The panel's product specification can be found at:

v1->v2:
* Use struct display_timing to tell minimum and maximum pixel clock rates.
* Set bus_flags to DRM_BUS_FLAG_DE_HIGH in struct panel_desc.
