Hello!
This adds support for the STARRY XR109IA2T panel based on the hx83102 chip
Changes in v2:
- Corrected case for hexadecimal code.
- Uppercase characters have been replaced with lowercase in the panel initialization sequence.
Thanks

The STARRY XR109AI2T is a 10.95" 1200x2000 (WUXGA+) TFT LCD panel with
himax-hx83102 controller. Hence, we add a new compatible with panel
specific config.

The STARRY XR109AI2T is a 10.95" 1200x2000 (WUXGA+) TFT LCD panel with
