So far POWER7+ was a part of POWER7 family. However it has a different
PVR base value so in order to support PVR masks, it needs a separate
family class.
This adds a new family class, PVR base and mask values and moves
Power7+ v2.1 CPU to a new family. The class init function is copied
from the POWER7 family.
This defines a firmware name for the new family as "PowerPC,POWER7+"
instead of previously used "PowerPC,POWER7" from the POWER7 family.
The reason for that is that the Sapphire firmware (a h0st firmware)
uses "PowerPC,POWER7+" already and since no specification defines
exactly the CPU nodes naming in the device tree, we better stay
in sync with the host firmware.

IBM POWERPC processors encode PVR as a CPU family in higher 16 bits and
a CPU version in lower 16 bits. Since there is no significant change
in behavior between versions, there is no point to add every single CPU
version in QEMU's CPU list. Also, new CPU versions of already supported
CPU won't break the existing code.
This adds PVR value/mask support for KVM, i.e. for -cpu host option.
As CPU family class name for POWER7 is "POWER7-family", there is no need
to touch aliases.

Commit 03a15a5436 claimed to add a POWER7+
model but instead added a "POWER7P" model, with an unhelpful "POWER7P"
description on top. Fix this to "POWER7+" as we already have "POWER3+",
"POWER4+" and "POWER5+" and there being no reason to deviate with the
user-visible command line -cpu POWER7P from the marketing name POWER7+.
Further, don't needlessly deviate from the scheme of naming PVR constant,
QOM type and device description after the exact revision that is in fact
encoded in the PVR used.
That way, we can change the user-friendly alias -cpu POWER7+ to point to a
different revision if we so desire, while not polluting the type namespace.
This naming scheme is sensible and completely orthogonal to how PVRs may
or may not get matched to CPU types.

MPC86xx processors are based on the e600 core, which is not the case
in qemu where it is based on the 7400 processor.
This patch creates the e600 core and instantiates the MPC86xx
processors based on it. Therefore, adding the high BATs, the SPRG
4..7 registers, which are e600-specific [1], and a HW MMU model (as 7400).
This allows to define the MPC8610 processor too.
Tested with a kernel using the HW TLB misses.

When running QEMU with "-cpu ?" we walk through every alias for every
target CPU we know about. This takes several seconds on my very fast
host system.
Let's introduce a class object cache in the alias table. Using that we
don't have to go through the tedious work of finding our target class.
Instead, we can just go directly from the alias name to the target class
pointer.
This patch brings -cpu "?" to reasonable times again.

The PowerPC 620 was the very first 64-bit PowerPC implementation, but
hardly anyone ever actually used the chips. qemu notionally supports the
620, but since we don't actually have code to implement the segment table,
the support is broken (quite likely in other ways too).
This patch, therefore, removes all remaining pieces of 620 support, to
stop it cluttering up the platforms we actually care about. This includes
removing support for the ASR register, used only on segment table based
machines.
