drm/amd/display: Optimizations for DML math

Browse Source 
[why]
Conditionals in the DML basic math functions significantly impact mode
enumeration.

[how]
Remove conditionals for floor/ceil operations which are used frequently
in DML and add an assertion for invalid callers using zero granuality.
Fix existing callers that rely on 0 granularity.
