ppc: Fix compilation for ppc64-softmmu

When QEMU was configured with --enable-debug-tcg,
compilation fails in spr_write_booke206_mmucsr0() and in
spr_write_booke_pid(). Similar changes are also needed
in conditional code which is normally unused.

PPC: Add another 64 bits to instruction feature mask

To enable quick runtime detection of instruction groups to the currently

instruction supports.

This feature mask is 64 bits long and we just successfully exceeded those 64...

PPC: Implement e500 (FSL) MMU

Most of the code to support e500 style MMUs is already in place, but
we're missing on some of the special TLB0-TLB1 handling code and slightly

This patch adds support for the FSL style MMU.

    later PowerPC implementation.
  • Bugfix in BATs check: must not stop after 4 BATs when more are provided.
  • Enable POWER 'rac' instruction.
