    sh: use ctrl_in/out for on chip pci access
    
    This patch makes sure ctrl_inN/outN are used instead of inN/outN for
on chip
    pci registers. Without this patch addresses may be adjusted using
the value
    in generic_io_base. This patch makes it possible to set
generic_io_base and
    have pci without reading and writing all over the place.
