2019-10-03drm/amd/display: Revert fixup DPP programming sequenceWesley Chalmers

2019-08-15drm/amd/display: fixup DPP programming sequenceJun Lei
[why] DC does not correct account for the fact that DPP DTO is double buffered while DPP ref is not. This means that when DPP ref clock is lowered when it's "safe to lower", the DPP blocks that need an increased divider will temporarily have actual DPP clock drop below minimum while DTO double buffering takes effect. This results in temporary underflow. [how] To fix this, DPP clock cannot be programmed atomically, but rather be broken up into the DTO and the ref. Each has a separate "safe to lower" logic. When doing "prepare" the ref and dividers may only increase. When doing "optimize", both may decrease. It is guaranteed that we won't exceed max DPP clock because we do not use dividers larger than 1.
