[GIT PULL] PCI fixes for v3.17

[Bjorn Helgaas]

Hi Linus,

These fix:

- Boot video device detection on dual-GPU Apple systems
- Hotplug fiascos on VGA switcheroo with radeon & nouveau drivers
- Boot hang on Freescale i.MX6 systems
- Excessive "no hotplug settings from platform" warnings

Hi Linus,

Here are a few fixes that should be in v3.17.

- Reverting "Don't scan random busses" covers up a CardBus regression
having to do with allocating CardBus bus numbers.

- Reverting "Make sure bus numbers stay within parents bounds" covers up
an ACPI _CRS bug that makes us reconfigure a bridge, causing a broken
device behind it to stop responding.

- The pciehp timeout change fixes some code we added in v3.17. Without
the fix, we can send a new hotplug command too early, before the
timeout has expired.

I hope for better fixes for the reverts, but those will have to come after
v3.17.

Bjorn
