Subject: [PATCH 0/6] Add SMEM-based speedbin matching

Newer (SM8550+) SoCs don't seem to have a nice speedbin fuse anymore,
but instead rely on a set of combinations of "feature code" (FC) and
"product code" (PC) identifiers to match the bins. This series adds
support for that.

I suppose a qcom/for-soc immutable branch would be in order if we want
to land this in the upcoming cycle.

FWIW I preferred the fuses myself..
