drm/panthor: Move cache-flush after UPDATE(UNMAPPED)
Right now, there's a theoretical window during which the GPU can populate
the cache with data from a VM that's about to be evicted through the
UPDATE(UNMAPPED) command.
In practice this won't happen (hence the absence of Fixes tag) because
when panthor_mmu_as_disable() is called, the VM is guaranteed to be idle
(no active CSG pointing to this VM), but as we say, better safe than
sorry.
