Merge remote-tracking branch 'remotes/mst/tags/for_upstream' into staging

pc,virtio,pci: fixes and updates

Most notably, this includes the TCO support for ICH: the last feature for 2.4
as we are entering the hard freeze.

Bugfixes only from now on.

virtio pci also gained cfg access capability - arguably a bugfix
since virtio spec makes it mandatory, but it's a big patch.
