Move request_standard_resources() back to before PCI probing

Browse source 
This effectively undoes the PCI resource allocation changes done in
commit b408cbc704, but leaves the cleanups
of that commit in place.

We're going back to marking the resources reported by e820 busy _before_
doing PCI probing, so that any PCI resource that clashes with the BIOS-
reported memory map will be reloacted to a non-clashing area.

The reason? Larry Finger reports that his laptop has the cardbus
controller set up by the BIOS so that it conflicts with the e820 memory
map, and needs to be relocated. See

   http://bugzilla.kernel.org/show_bug.cgi?id=6337

for more details.

We'll have to work out how to handle the fbcon problem that caused that
commit in the first place in some other way.
