[PATCH 0/3] Enable GuC SLPC default balancing strategies v2

[Rodrigo Vivi]

The goal here is to improve the GPU performance in some cases
where we are TDP limited, with both GPU and CPU with high
utilization and PCODE without power to fulfill both sides.
Of course, only matters for integrated parts with GuC
SLPC enabled: ADL and MTL.

Apparently the ADL on our CI was not happy about that
with the igt_spinners timming out [1]. So, this new attempt
also lift the BAT restriction on the igt_spinner with the
first patch.

Another possibility would be to make this change for MTL
only, but I'm afraid that this is not the ideal, because:
1. ADL users couldn't get the performance benefit of this change
2. This would sound like a hack to bypass CI, where the ADL there
   might have some TDP limitation and MTL there having more power.
