From: Qingqing Zhuo <Qingqing.Zhuo@xxxxxxx>
[Why & How]
- Introduce DML2 for future ASIC support.
- DML2 supports mode verification and DCN programming
in display SW/HW.
- DML2 is written in C from the ground up, making it
easier to read and maintain in comparision to DML1
v2: fix typo (Alex)
v3: includes dc changes
