As it relies on primitive types that have already been ported
Aml::append_aml_bytes can be used for the child values.

Since we know all the numerical types now have implementations of
Aml::append_aml_bytes() we can use that directly.

As this is a DWord and we know that DWord::append_aml_bytes() is
implemented we may call it directly.

This is a naive implementation and there is scope to improve this
without extra copies but that requires addressing the users to ensure
there are no lifetime issues.

As an optimisation to avoid allocating byte vectors add a trait method
that will append to an existing vector. Further to support the
transition add a default implementation of Aml::to_aml_bytes() that uses
the newly added Aml::append_aml_bytes()

Now that vfio-ioctls correctly exposes the list of capabilities related
to each region, Cloud Hypervisor can decide to mmap a region based on
the presence or absence of MSIX_MAPPABLE. Instead of blindly mmap'ing
the region, we check if the MSI-X table or PBA is present on the BAR,
and if that's the case, we look for MSIX_MAPPABLE.
If MSIX_MAPPABLE is present, we can go ahead and mmap the entire region.
If MSIX_MAPPABLE is not present, we simply ignore the mmap'ing of this
region as it wouldn't be supported.

By merging receive buffers through the VIRTIO_NET_F_MRG_RXBUF feature,
as well as enabling the use of indirect descriptors through
VIRTIO_RING_F_INDIRECT_DESC feature, we achieve better throughput for
the virtio-net device without hurting its latency.

This allocator allocates 64-bit MMIO addresses for use with platform
devices e.g. ACPI control devices and ensures there is no overlap with
PCI address space ranges which can cause issues with PCI device
remapping.
Use this allocator the ACPI platform devices.

Rather than use the system MMIO allocator for RAM use an allocator that
covers the full RAM range.
