drm/amd/display: Fix Chroma Surface height/width initialization

[why]
Surface height/width for Chroma has another variable that it should be
intialized to, chroma_size. Fixing this will help pass DML2.0 validation
for YCbCr420 tests, DCHB006.109,129, DCHB014.011,012.

[how]
Assign SurfaceHeight/WidthC to chroma_size.height/width
