Configure a panfrost performance structure with tables of categories and
counters for the current product id. An array for storing counter values
read from the GPU is also managed by this structure. A generic read
function can be used to retrieve the value of a counter from the conter
values array.
v2: Generate tables instead of calling register functions.
v3: Simplify counter read function and `pan_gen_perf.py` write method.
v4: Accumulate counter values from all cores.
v5: Wrap `STATIC_ASSERT`s within unused functions.
