etnaviv: flush depth cache when changing depth config

Browse source 
Some depth config states changes require the depth cache to be
flushed, leading to a GPU hang if not done. As the conditions that
require the flush are not toally clear, better be safe than sorry
and always flush the cache on depth state changes.
