ppc/spapr: Initialize max_cpus limit to SPAPR_IRQ_NR_IPIS.

Initialize the machine specific max_cpus limit as per the maximum range
of CPU IPIs available. Keeping between 4096 to 8192 will throw IRQ not
free error due to XIVE/XICS limitation and keeping beyond 8192 will hit
assert in tcg_region_init or spapr_xive_claim_irq.

usb-storage: Fix BlockConf defaults

Commit 30896374 started to pass the full BlockConf from usb-storage to
scsi-disk, while previously only a few select properties would be
forwarded. This enables the user to set more properties, e.g. the block
size, that are actually taking effect.

However, now the calls to blkconf_apply_backend_options() and
blkconf_blocksizes() in usb_msd_storage_realize() that modify some of
these properties take effect, too, instead of being silently ignored.
This means at least that the block sizes get an unconditional default of
512 bytes before the configuration is passed to scsi-disk.

Before commit 30896374, the property wouldn't be set for scsi-disk and
therefore the device dependent defaults would apply - 512 for scsi-hd,
but 2048 for scsi-cd. The latter default has now become 512, too, which
makes at least Windows 11 installation fail when installing from
usb-storage.

Fix this by simply not calling these functions any more in usb-storage
and passing BlockConf on unmodified (except for the BlockBackend). The
same functions are called by the SCSI code anyway and it sets the right
defaults for the actual media type.

Fixes: 308963746169 ('scsi: Don't ignore most usb-storage properties')

pc: Fix CMOS info for drives defined with -device

Drives defined with -drive if=ide get get created along with the IDE
controller, inside machine->init(). That's before cmos_init().
Drives defined with -device get created during generic device init.
That's after cmos_init(). Because of that, CMOS has no information on
them (type, geometry, translation). Older versions of Windows such as
XP reportedly choke on that.

Split off the part of CMOS initialization that needs to know about
-device devices, and turn it into a reset handler, so it runs after
device creation.

qcow2: Bring synchronous read/write back to life

When the synchronous read and write functions were dropped, they were replaced
by generic emulation functions. Unfortunately, these emulation functions don't
provide the same semantics as the original functions did.

The original bdrv_read would mean that we read some data synchronously and that
we won't be interrupted during this read. The latter assumption is no longer
true with the emulation function which needs to use qemu_aio_poll and therefore
allows the callback of any other concurrent AIO request to be run during the
read. Which in turn means that (meta)data read earlier could have changed and
be invalid now. qcow2 is not prepared to work in this way and it's just scary
how many places there are where other requests could run.

I'm not sure yet where exactly it breaks, but you'll see breakage with virtio
on qcow2 with a backing file. Providing synchronous functions again fixes the
problem for me.
