When FreeBSD is running as dom0 (initial domain) on a Xen system it has access to the native ACPI tables and is the OSPM. However the hypervisor is the entity in charge of the CPU idle and frequency states, and in order to perform this duty it requires information found the ACPI dynamic tables that can only be parsed by the OSPM. Introduce a new Xen specific ACPI driver to fetch the Processor related information and upload it to Xen. Note that this driver needs to take precedence over the generic ACPI CPU driver when running as dom0, so downgrade the probe score of the native driver to BUS_PROBE_DEFAULT in order for the Xen specific driver to use BUS_PROBE_SPECIFIC. Tested on an Intel NUC to successfully parse and upload both the Cx and Px states to Xen.
