drm/amd/display: limit clear_update_flags to dcn32 and above

[ Upstream commit f354556e29f40ef44fa8b13dc914817db3537e20 ]

[why]
dc has some code out of sync:
dc_commit_updates_for_stream handles v1/v2/v3,
but dc_update_planes_and_stream makes v1 asic to use v2.

as a reression fix: limit clear_update_flags to dcn32 or newer asic.
need to follow up that v1 asic using v2 issue.
