MIPS: SGI-IP27: fix exception handler replication
Commit 775b089aeffa ("MIPS: tlbex: Remove cpu_has_local_ebase") removed generating tlb refill handlers for every CPU, which was needed for generating per node exception handlers on IP27. Instead of resurrecting (and fixing) refill handler generation, we simply copy all exception vectors from the boot node to the other nodes. Also remove the config option since the memory tradeoff for expection handler replication is just 8k per node.
