Save the IRQ that we get in pci attachment.

Print type of pci bridge we find.
Force the IRQ of pci bridges upon all its children.
Allocate the resources on behalf of the bridge when we're testing to see if
they exist.

This should help people who don't read updating instructions very well.

This patch started out with an idea from Shigeru Yamamoto-san in -current.
