[PATCH v2 02/12] drm/amd/display: Rework context change check

[Rodrigo Siqueira]

Context change is all about streams; for this reason, this commit
renames context_changed to streams_changed. Additionally, to make this
function more flexible, this commit changes the function signature to
receive the stream array and the stream count as a parameter.
