Konrad Rzeszutek Wilk 5d55ddd882 linux-xencommons: Load xen-acpi-processor
Upstream the "xen/acpi-processor: C and P-state driver that
uploads said data to hypervisor." takes care of uploading power information
information that normally a cpu frequency scaling driver would using
in the initial domain. We want the hypervisor to take that data and
make good usage of it.

Fortunatly for us we do not have to worry about the native cpu frequency
scaling drivers being loaded first, as the upstream commit:
"xen/cpufreq: Disable the cpu frequency scaling drivers from loading."
takes care of that. Meaning we can load the xen-acpi-processor at any time.

By default that driver is built as a module - and since we are
the only user of it - we should load it.
