Fabiano Rosas b137fb72d7 target/ppc: Disable unused facilities in the e600 CPU 
The e600 CPU is a successor of the 7448 and like all the 7450s CPUs,
it has an optional software TLB feature.

We have determined that there is no OS software support for the 7450
software TLB available these days. See the previous commit for more
information.

This patch disables the SPRs and instructions related to software TLB
from the e600 CPU.

No functional change intended. These facilities should be used by the
OS in interrupt handlers for interrupts that QEMU never generates.
