Oh look, Intel have released a *third* version of that document
already, and they've bumped the bad Kabylake versions to 0x84, although
they're *still* missing out the KBL 906EA SKU which was updated to 0x80
in the public 20180108 microcode release. I'll bump them all in my tree
to 0x84.

Thomas, want another copy in email now, or were we waiting for another
round of these before you merge them anyway?
