Make the 11MPCore report a valid value in its cache type register
(the previous value appears to have been incorrectly copied from
the 1136/1176). In particular, do not report that we have an
aliasing VIPT cache, because this causes Linux to attempt to use
the v6 block cache ops which the 11MPCore doesn't actually have.
(This causes no problems currently because we over-broadly provide
those ops on all cores, but prevents us correctly narrowing the
block ops down to those cores which actually implement them.)

QEMU exposes its version to the guest's hardware and in some cases that is wrong
(e.g. Windows prints messages about driver updates when you switch
the QEMU version).
There is a new field now on the struct QEmuMachine, hw_version, which may
contain the version that the specific machine should report. If that field is
set, then that machine will report that version to the guest.

This patch adds two things. First it allows QEMU to distinguish between
regular powerdown and S4 powerdown. Later separate QMP notification will
be added for S4 powerdown. Second it allows S3/S4 states to be disabled
from QEMU command line. Some guests known to be broken with regards to
power management, but allow to use it anyway. Using new properties
management will be able to disable S3/S4 for such guests.

Supported system state are passed to a firmware using new fw_cfg file.
The file contains  6 byte array. Each byte represents one system
state. If byte at offset X has its MSB set it means that system state
X is supported and to enter it guest should use the value from lowest 3
bits.

This is far less interesting than it sounds.  We simply add an Object to each
BusState and then register the types appropriately.  Most of the interesting
refactoring will follow in the next patches.

Since we're changing fundamental type names (BusInfo -> BusClass), it all needs
to convert at once.  Fortunately, not a lot of code is affected.

Now that global properties do not depend on buses anymore, set
them directly in the device instance_init function.
Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>
Signed-off-by: NAndreas Färber <afaerber@suse.de>

In qdev, each bus in practice identified an abstract superclass, but
this was mostly hidden.  In QOM, instead, these abstract classes are
explicit so we can move bus properties there.

All bus property walks are removed, and all device property walks
are changed to look along the class hierarchy instead.

We would have duplicates if class A defines some properties and its
subclass B does not define any, because class_b->props will be
left equal to class_a->props.

The solution here is to reintroduce the class_base_init TypeInfo
callback, that was present in one of the early QOM versions but
removed (on my request...) before committing.

This breaks global bus properties, an obscure feature when used
with the command-line which is actually useful and used when used by
backwards-compatible machine types.  So this patch also adjusts the
global bus properties in hw/pc_piix.c to refer to the abstract class.

Globals and other properties must be modified in the same patch to
avoid complications related to initialization ordering.
