sparc32: introduce asm-generic

Inspired by Michal Simek <[email protected]> this patch-set introduces asm-generic/io.h for sparc32.

As the diff-stat tells this was a nice code-reduction.

The changes are done on top of the previous sent sparse warning cleanup. But I do not expect any difficult conflicts if applied alone.

leon_pci + pcic are touched because they had local and identical implementations of functiones that are static inline in asm-generic/io.h

leon_pci_grpci1 + leon_pci_grpci2 are touched becuse they used a sparc spacific implmentation of swab32. They have just been changed to use the global variant.

I also looked at sparc64 - but there were to many sparc64 assembler implementations of the io functons - and the generic io.h did not support this mix.

The last patch kills a few defines in io.h for sbus. I assume they were introduced before the functions were all shifted over to __iomem style pointers. The same could be done for sparc64 - but then there were even more of the same so I left this for another time.

The patch-set has been build tested only. My attempts to test this using qemu have failed as the qemu version I have errors out.
And my fedora box are mssing some libs to build qemu from source :-(
