[PULL 61/62] qapi: Add 'acpi' field to 'query-machines' output

[Paolo Bonzini]

From: Peter Krempa <pkrempa@redhat.com>

Report which machine types support ACPI so that management applications
can properly use the 'acpi' property even on platforms such as ARM where
support for ACPI depends on the machine type and thus checking presence
of '-machine acpi=' in 'query-command-line-options' is insufficient.
