Clean up mostly unused IOSPACE macros

Most architectures defined three macros, MK_IOSPACE_PFN(), GET_IOSPACE()
and GET_PFN() in pgtable.h.  However, the only callers of any of these
macros are in Sparc specific code, either in arch/sparc, arch/sparc64 or
drivers/sbus.

This patch removes the redundant macros from all architectures except
sparc and sparc64.
