parisc: hide ioread64 declaration on 32-bit

The definition of ioread64 etc is hidden on 32-bit, but the declaration
remained by accident, which led to the generic definition getting left
out:

ERROR: modpost: "ioread64" [drivers/pci/switch/switchtec.ko] undefined!

Hide the declaration and #define under the same #ifdef.
