drm/amd/display: Add Underflow Asserts to dc
[Why]
For debugging underflow issues it can be useful to have asserts when the
underflow initially occurs.
[How]
Read the underflow status registers after actions that have a high risk
of causing underflow and assert that no underflow occurred. If underflow
occurred, clear the bit.
