In response to v2, Ilpo gave a heads-up that the first patch in the series
was problematic:  A zero Max Link Speed is common in particular on Root
Complex Integrated Endpoints, so there's no reason to emit a warning
or assume 2.5 GT/s.

In the interest of resolving the regression before the holidays,
I'm respinning already after two days and I'm reverting back to my
original proposal to use 0 as lowest bit in the GENMASK() macro.
I've amended the commit message with an explanation to address Ilpo's
concern that the 0 may cause confusion because Supported Link Speeds
ends at bit 1.

So patch [1/2] in this series is identical to what's already queued up
on pci.git/for-linus, save for the extended commit message.

And patch [2/2] is unchanged vis-à-vis v2.

  PCI: Honor Max Link Speed when determining supported speeds
  PCI/bwctrl: Enable only if more than one speed is supported
