panfrost: Disable frame throttling

The new frame throttling implemention interacts unfortunately with
pipelining, leading to fence fds leaking like crazy and ultimately apps
crashing quickly.

With this patch, apps still crash but not as quickly. We need to either
figure out the real cause or revert the core changes.

Nevertheless, we don't want frame throttling in the first place, so.
