[PARISC] Fix Cirrus 6832 Cardbus on RDI Tadpole PARISC Laptop

Fix irq-off-by-one for Cirrus 6832 Cardbus on RDI Tadpole PARISC Laptop. We just DECLARE_PCI_FIXUP_ENABLE as it is unlikely that this will be found in any other parisc system. Signed-off-by: Helge Deller <[email protected]> Signed-off-by: Kyle McMartin <[email protected]>
