hw: Avoid use of QOM type name macros in VMStateDescriptions

The name field in a VMStateDescription is part of the migration state
versioning, so changing it will break migration.  It's therefore a
bad idea to use a QOM typename macro to initialize it, because in
general we're free to rename QOM types as part of code refactoring
and cleanup.  For the handful of devices that were doing this by
mistake, replace the QOM typenames with the corresponding literal

virtio: Support transports which can specify the vring alignment

Support virtio transports which can specify the vring alignment
(ie where the guest communicates this to the host) by providing
a new virtio_queue_set_align() function. (The default alignment
remains as before.)

Transports which wish to make use of this must set the
has_variable_vring_alignment field in their VirtioBusClass
struct to true; they can then change the alignment via
virtio_queue_set_align().

device_tree: Add qemu_devtree_setprop_sized_cells() utility functions

We already have a qemu_devtree_setprop_cells() which sets a dtb
property to an array of cells whose values are specified by varargs.
However for the fairly common case of setting a property to a list
of addresses or of address,size pairs the number of cells used by
each element in the list depends on the parent's #address-cells
and #size-cells properties. To make this easier we provide an analogous
qemu_devtree_setprop_sized_cells() macro which allows the number
of cells used by each element to be specified. This is implemented
using an underlying qemu_devtree_setprop_sized_cells_from_array()
function which takes the values and sizes as an array; this may
also be directly useful for cases where the cell contents are
constructed programmatically.
