Add a node for the aspeed-p2a-ctrl module. This node, when enabled will
disable the PCI-to-AHB bridge and then allow control of this bridge via
ioctls, and access via mmap.

Patrick,
Please send these to Joel and Andrew (and cc the mailing lists). No need to
send patches that there are active maintainers for to [email protected] directly.
(As a matter of fact, drivers/soc/aspeed should go through them too, even if
I applied the first patch directly just now).
