2024-09-18drm/amd/display: Use SDR white level to calculate matrix coefficientsSamson Tam2-7/+12
[WHY] Certain profiles have higher HDR multiplier than SDR white level max which is not currently supported. [HOW] Use SDR white level when calculating matrix coefficients for HDR RGB MPO path instead of HDR multiplier.

[WHAT & HOW] Integer multiplies integer may overflow in context that expects an expression of unsigned/siged long long (64 bits). This can be fixed by casting integer to unsigned/siged long long to force 64 bits results. This fixes 26 OVERFLOW_BEFORE_WIDEN issues reported by Coverity.
