drm/amd/display: update MSA and VSC SDP on video test pattern request

[why]
On video test pattern request we need to update MSA and VSC so
it will match the requested test pattern dynamic range field.

[how]
Update dynamic range field in MSA and disable VSC as updating VSC
info packet is complicated and not required for test pattern purpose.
