Christophe Leroy 70d6ebf82b powerpc/603: Avoid a pile of NOPs when not using SW LRU in TLB exceptions 
The SW LRU is in an MMU feature section. When not used, that's a
dozen of NOPs to fetch for nothing.

Define an ALT section that does the few remaining operations.

That also avoids a double read on SRR1 in the SW LRU case.
