[PATCH] pci and yenta: pcibios_bus_to_resource

In yenta_socket, we default to using the resource setting of the CardBus
bridge.  However, this is a PCI-bus-centric view of resources and thus needs
to be converted to generic resources first.  Therefore, add a call to
pcibios_bus_to_resource() call in between.  This function is a mere wrapper on
x86 and friends, however on some others it already exists, is added in this
patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where
is its pcibios_resource_to_bus() ?).
