Hoegeun Kwon e2af12bfb0 drm/panel: s6e3ha2: Add support for s6e3hf2 panel on TM2e board 
This patch supports TM2e panel and the panel has 1600x2560 resolution
in 5.65" physical.

This identify panel type with compatibility string, also invoke
display mode that matches the type. So add the check code for s6e3ha2
