drm/amd/display: Fix dml2_0 narrowing boundaries

Browse source

[Why] drm/amd/display dml2_0 code had implicit narrowing conversions reported by
a warning in timing, watermark, and translation paths.

[How] Apply explicit boundary casts for intentional narrowing, preserve wider
intermediate math, and use wider timing intermediates where required for safe
range handling.
