Sparc32: implement AFX for SS-5
Implement a stub for the AFX register on SparcStation-5. This stub is needed for running the original SS-5 OBP instead of OpenBIOS (which allows to boot Solaris 2.5.1 and Solaris 2.6 kernels). Signed-off-by: Artyom Tarasenko <atar4qemu@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
