drm/amd/display: Clear update flags at end of flip



Clear update flags so the next flip does not have any redundant
programming (if a subsequent flip does not have a stream or plane
update, the update flags are not cleared).

Fixes: 0baae624 ("drm/amd/display: Refactor fast update to use new HWSS build sequence")
