The bindings for the V3 Semiconductor PCI bridge are a tad bit outdated
and predates the more formal format we have adopted for the bindings.
Update them a bit so it is easier to read, and add the Integrator AP-
specific compatible so we can detect that we are running on that specific
platform.

Acked-by: Rob Herring <robh@kernel.org>

ChangeLog v1->v2:
- Added Rob's ACK.

Bjorn: please merge this when you feel confident with it.
