The Ibex core contains a PLIC that although similar to the RISC-V spec
is not RISC-V spec compliant.
This patch implements a Ibex PLIC in a somewhat generic way.
As the current RISC-V PLIC needs tidying up, my hope is that as the Ibex
PLIC move towards spec compliance this PLIC implementation can be
updated until it can replace the current PLIC.

Suggest VIRTIO_NET_F_HASH_REPORT if specified in device
parameters.
If the VIRTIO_NET_F_HASH_REPORT is set,
the device extends configuration space. If the feature
is negotiated, the packet layout is extended to
accomodate the hash information. In this case deliver
packet's hash value and report type in virtio header
extension.
Use for configuration the same procedure as already
used for RSS. We add two fields in rss_data that
controls what the device does with the calculated hash
if rss_data.enabled is set. If field 'populate' is set
the hash is set in the packet, if field 'redirect' is
set the hash is used to decide the queue to place the
packet to.

Convert all size-related properties in BlockConf to 32bit. This will
accommodate bigger block sizes (in a followup patch). This also allows
to make them all accept size suffixes, either via DEFINE_PROP_BLOCKSIZE
or via DEFINE_PROP_SIZE32.
Also, since min_io_size is exposed to the guest by scsi and virtio-blk
devices as an uint16_t in units of logical blocks, introduce an
additional check in blkconf_blocksizes to prevent its silent truncation.

Introduce size32 property type which handles size suffixes (k, m, g)
just like size property, but is uint32_t rather than uint64_t. It's
going to be useful for properties that are byte sizes but are inherently
32bit, like BlkConf.opt_io_size or .discard_granularity (they are
switched to this new property type in a followup commit).
The getter for size32 is left out for a separate patch as its benefit is
less obvious, and it affects test output; for now the regular uint32
getter is used.

Several block device properties related to blocksize configuration must
be in certain relationship WRT each other: physical block must be no
smaller than logical block; min_io_size, opt_io_size, and
discard_granularity must be a multiple of a logical block.
To ensure these requirements are met, add corresponding consistency
checks to blkconf_blocksizes, adjusting its signature to communicate
possible error to the caller. Also remove the now redundant consistency
checks from the specific devices.

On restart, we were scheduling a BH to process queued requests, which
would run before starting up the data plane, leading to those requests
being assigned and started on coroutines on the main context.
This could cause requests to be wrongly processed in parallel from
different threads (the main thread and the iothread managing the data
plane), potentially leading to multiple issues.
For example, stopping and resuming a VM multiple times while the guest
is generating I/O on a virtio_blk device can trigger a crash with a
stack tracing looking like this one:

We convert queued work to a QSIMPLEQ, instead of
open-coding it.
While at it, make sure that all accesses to the list are
performed while holding the list's lock.

The Linux kernel's IMX code now uses vendor specific commands.
This results in endless warnings when booting the Linux kernel.
sdhci-esdhc-imx 2194000.usdhc: esdhc_wait_for_card_clock_gate_off:
card clock still not gate off in 100us!.
Implement support for the vendor specific command implemented in IMX hardware
to be able to avoid this warning.

Sysbus devices almost always plug into the main system bus.
qdev_create() even has a convenience feature to make that easy: a null
bus argument gets replaced by the main system bus. qdev_realize() and
qdev_realize_and_unref() do the same.
We can do better. Provide convenience wrappers around qdev_realize()
and qdev_realize_and_unref() that don't take a @bus argument. They
always pass the main system bus.

ssi_auto_connect_slaves(parent, cs_line, bus) iterates over @parent's
QOM children @dev of type TYPE_SSI_SLAVE. It puts these on @bus, and
sets cs_line[] to qdev_get_gpio_in_named(dev, SSI_GPIO_CS, 0).
Suspicious: there is no protection against overrunning cs_line[].
Turns out it's safe because ssi_auto_connect_slaves() never finds any
such children. Its called by realize methods of some (but not all)
devices providing an SSI bus, and gets passed the device.
SSI slave devices are always created with ssi_create_slave_no_init(),
optionally via ssi_create_slave(). This adds them to their SSI bus.
It doesn't set their QOM parent.
ssi_create_slave_no_init() is always immediately followed by
qdev_init_nofail(), with no QOM parent assigned, so
device_set_realized() puts the device into the /machine/unattached/
orphanage. None become QOM children of a device providing an SSI bus.
ssi_auto_connect_slaves() was added in commit b4ae3cfa57 "ssi: Add
slave autoconnect helper". I can't see which slaves it was supposed
to connect back then.
