M2 Unknown microarchitecture (expected cpu part differs from kernel)

[Oery]

Happening on a Macbook Air M2 running nixos.

cpufetch expects cpu parts 0x030/0x031 for Avalanche/Blizzard but I get 0x032/0x33, which should be the correct values according to the linux kernel, now that they are available.
