From: "Srivatsa, Anusha" <anusha.srivatsa@xxxxxxxxx>
Add defines for DSS_CTL registers.
These registers specify the big joiner, splitter,
overlap pixels and info regarding display stream
compression enabled on left or right branch.
v3 (From Manasi):
- Change the hex values to lower case (Madhav)
- Use BIT macro (Manasi)
v2:
- Add define to conditionally check the buffer target depth (James Ausmus)
