drm/panfrost: Perform hard reset to recover GPU if soft reset fails
Even though soft reset should ideally never fail, during development of
some power management features I managed to get some bits wrong: this
resulted in GPU soft reset failures, where the GPU was never able to
recover, not even after suspend/resume cycles, meaning that the only
way to get functionality back was to reboot the machine.
Perform a hard reset after a soft reset failure to be able to recover
the GPU during runtime (so, without any machine reboot).
