drm/panfrost: Simplify devfreq utilisation tracking
Instead of tracking per-slot utilisation track a single value for the entire GPU. Ultimately it doesn't matter if the GPU is busy with only vertex or a combination of vertex and fragment processing - if it's busy then it's busy and devfreq should be scaling appropriately. This also makes way for being able to submit multiple jobs per slot which requires more values than the original boolean per slot.
