drm/amd/display: Do DML float narrowing explicit

[Why]
Shared DML wrapper helpers in [dc/dml/dml_inline_defs.h](dc/dml/dml_inline_defs.h)
pass double and int values to float-based dcn_bw_* helpers. Make these
intentional narrowing boundaries explicit to reduce warning noise
without changing behavior.

[How]
Add explicit C-style casts at the float API boundary in the shared DML
inline wrappers used by the DCN DML paths.
