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.
