drm/panel-simple: Add Innolux G156HCE-L01 panel entry

Browse source 
Add support for Innolux G156HCE-L01 15.6" 1920x1080 24bpp
dual-link LVDS TFT panel. Documentation is available at [1].
The middle frequency is tuned slightly upward from 70.93 MHz
to 72 MHz, otherwise the panel shows slight flicker.
