mali_kbase: dvfs: add min gpu level for compute.
Adds a DTBO entry that can be used to set the minimum dvfs OPP when
compute contexts are detected running. This effectively uses compute as
a proxy signal that there are realtime workloads present
Bug: 178234323
Test: tflite does up gpu frequency.
Test: UI does not up gpu frequency.
