Adrián Larumbe 7de295d1a1 drm/panthor: flush FW AS caches in slow reset path ...

In the off-chance that waiting for the firmware to signal its booted status
timed out in the fast reset path, one must flush the cache lines for the
entire FW VM address space before reloading the regions, otherwise stale
values eventually lead to a scheduler job timeout.
