gpu-aml: Do not use Mali Utilization

This settings turns off any scaling for Mali cores/frequency.
The effect of this is smooth Kodi GUI operation without a need
to set turbo mode in driver parameter or device tree.

Users reported smoother GUI with UTILIZATION = 0 and Mali operating at 500MHz
than with UTILIZATION = 1 and Mali at 666MHz.
