Josip Pavic 615fc50207 drm/amd/display: Avoid MPC infinite loop
[Why]
In some cases MPC tree bottom pipe ends up point to itself.  This causes
iterating from top to bottom to hang the system in an infinite loop.

[How]
When looping to next MPC bottom pipe, check that the pointer is not same
as current to avoid infinite loop.
