I've made a patch that demonstrates what I have in mind, and
should work in general. With this patch, a configuration can
enable CONFIG_XILINX_OCP and enable CONFIG_XILINX_SYSACE and
not have ppc405gpr pci setup or PIC setup messed with.

Patch is relative the ppc.bkbits.net linuxppc-2.4 tree. I'm
guessing Andrei is the authority for this aspect.
