_DSM (Device Specific Method) is a control method that enables devices
to provide device specific control functions. Linux kernel will evaluate
this device then initialize preserve_config in acpi pci initialization.

On nightly, clippy expects the structs to be constructed with fields in
the same order they're declared in. Seems sensible enough, so let's do
that.

A new version of vm-memory was released upstream which resulted in some
components pulling in that new version. Update the version number used
to point to the latest version but continue to use our patched version
due to the fix for #1258

Ensure that the width of the I/O port is correctly set to 32-bits in the
generic address used for the X_PM_TMR_BLK. Do this by type
parameterising GenericAddress::io_port_address() fuction.
TEST=Boot with clocksource=acpi_pm and observe no errors in the dmesg.

These fields allow you to expose the component part of an existing
buffer, such as a resource template as a new field which is required to
expose the memory CRS details.

This is necessary as adding support for NamedFields requires a PkgLength
calculation that does not include the length itself.

Packages are a way of grouping values together and as such they require
an explicit length which is a variable length encoding calculated with
create_pkg_length().
