drm/vc4: bo: Add a managed action to cleanup the cache
[ Upstream commit 1c80be48c70a2198f7cf04a546b3805b92293ac6 ]
The BO cache needs to be cleaned up using vc4_bo_cache_destroy, but it's
not used consistently (vc4_drv's bind calls it in its error path, but
doesn't in unbind), and we can make that automatic through a managed
action. Let's remove the requirement to call vc4_bo_cache_destroy.
Fixes: c826a6e10644 ("drm/vc4: Add a BO cache.")
