  target-ppc: Fix breakpoint registers for e300

In the previous patch, the registers were added to init_proc_G2LE
instead of init_proc_e300.

  kvm: Fix memory slot page alignment logic

Memory slots have to be page aligned to get entered into KVM. There
is existing logic that tries to ensure that we pad memory slots that
are not page aligned to the biggest region that would still fit in the
alignment requirements.

Unfortunately, that logic is broken. It tries to calculate the start
offset based on the region size.

Fix up the logic to do the thing it was intended to do and document it
properly in the comment above it.

With this patch applied, I can successfully run an e500 guest with more
than 3GB RAM (at which point RAM starts overlapping subpage memory regions).

  target-ppc: Altivec's mtvscr Decodes Wrong Register

The Move to Vector Status and Control Register (mtvscr) instruction
uses VRB as the source register.  Fix the code generator to correctly
decode the VRB field.  That is, use "rB(ctx->opcode)" instead of
"rD(ctx->opcode)".
