Some of the GRPCI1 cores does not support detection of all PCI

The property all_pci_errors my be set by the boot loader to
enable interrupt on all PCI errors.

Please - use SPARC_ prefix.
All arch specific symbols shall have the ARCH_ prefix.
In the x86 world we do: X86_32_ for the 32 bit specific symbols.
I know someone(*) added a SPARC32_SMP - but thats not a good example to follow.
(*) Yeah - that was me. I got wiser now.

Sam and Dave, sorry for messing up this simple stuff. I simply did a typo. I appreciate your time and effort regarding this. I will update the two last patches shortly using SPARC_* instead.
