drm/amd/display: Fix narrowing boundaries in dml

Browse source

[Why]
DML code paths include implicit integer narrowing at protocol and
storage boundaries. Making these boundaries explicit improves clarity
and reduces warning noise while preserving behavior.

[How]
Apply explicit C-style casts at intentional narrowing boundaries
across DML calculation, mode support, RQ/DLG, wrapper, and DSC
helper paths.
Keep intermediate arithmetic in natural-width types where practical,
with minor type-consistency cleanups where needed. Add explicit
boundary casts for intentional narrowing and keep intermediate math
in wider types where practical, with small type-consistency cleanups
to maintain behavior and readability.
