[Patch 1/12] ACPI based root bridge hot-add

When you hot-plug a (root) bridge hierarchy, it may have p2p
bridges and devices attached to it that have not been configured
by firmware. In this case, we need to configure the devices 
before starting them. This patch separates device start from
device scan so that we can introduce the configuration step in
the middle. 

I kept the existing semantics for pci_scan_bus() since there
are a huge number of callers to that function.

Also, I have no way of testing the changes I made to the parisc
files, so this needs review by those folks. Sorry for the massive
cross-post, this touches files in many different places.
