ci/freedreno: Detect the cheza power management bus error and restart.

This is an issue on the cheza platform, the theory is due to some old
firmware bug that will be fixed in future platforms.  Given that cheza was
a target that didn't get released and we expect future platforms to be
fixed, just detect the issue and restart.

I've noticed this error in my CI monitoring less than once a week.
