Before the code freeze I thought I'd check the original driver again,
and indeed there were a few changes we want to inherit.

1: mention assumption that WBINVD is not needed
2: add SnowRidge C-state table
3: update ICX C6 data
4: add Icelake-D support
5: adjust the SKX C6 parameters if PC6 is disabled
