PPC: E500: Populate L1CFG0 SPR

When running Linux on e500 with powersave-nap enabled, Linux tries to
read out the L1CFG0 register and calculates some things from it. Passing
0 there ends up in a division by 0, resulting in -1, resulting in badness.

So let's populate the L1CFG0 register with reasonable defaults. That way...

PPC: E500: Add doorbell defines

We're going to introduce doorbell instructions (called processor
control in the spec) soon. Add some defines for easier patch
readability later.

PPC: Add CPU feature for processor control

We're soon going to implement processor control features. Add the
feature flag, so we're well prepared.

PPC: Enable doorbell excp handlers

We already had all the code available to have doorbell exceptions
be handled properly. It was just disabled.

Enable it, so we can rely on it.

PPC: E500: Implement msgclr

This patch implements the msgclr instruction. It is part of the
Embedded.Processor Control specification and clears pending doorbell
interrupts on the current CPU.

PPC: E500: Implement msgsnd

This patch implements the msgsnd instruction. It is part of the
Embedded.Processor Control specification and allows one CPU to
IPI another CPU without going through an interrupt controller.

PPC: e500mc: Enable processor control

The e500mc implements Embedded.Processor Control, so enable it and
thus enable guests to IPI each other. This makes -smp work with -cpu
e500mc.

PPC: booke206: move avail check to tlbwe

We can have TLBs that only support a single page size. This is defined
by the absence of the AVAIL flag in TLBnCFG. If this is the case, we
currently write invalid size info into the TLB, but override it on
internal fault....

PPC: E500: Add some more excp vectors

Our EXCP list is getting outdated. By now, 3 new exception vectors have
been introduced. Update the list so we have everything at one place.
