pci/host/fixes for v4.17-rc* - please pull

Hi Bjorn,

I have queued some fixes from Thomas and Loic on my pci/host/fixes branch:

https://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/pci.git/log/?h=pci/host/fixes

they are not necessarily urgent but they definitely fix issues (some longstanding) so I would kindly ask you to consider pulling that branch and send it upstream for v4.17-rc* cycles instead of waiting for the v4.18 patch queue.

Thank you (and Loic and Thomas for sending them) very much, Lorenzo

[+cc Evan, Victor because this also includes a few aardvark fixes]

I merged these to for-linus for v4.17, thanks!
