Yup, I noticed few commits that are trying to fix this. And these
fixes do work for PCI, but not for PCI-E...

Well. I see only two places were transparent flag is applied:
drivers/pci/quirks.c:quirk_transparent_bridge()
and
drivers/pci/probe.c:pci_setup_device() in the PCI_HEADER_TYPE_BRIDGE.
So, obviously probe.c is skipping our PCI-E, thus not setting
transparent flag, no?

This is standalone setup.
