drm/amd/display: Rework context change check

Browse Source 
[ Upstream commit 10fdb0a11c555e0d6f7698d2874581d06e99ee71 ]

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.
