[Xen-devel] [RFC PATCH 6/7] cpufreq: make CPU Frequency scaling drivers visible for XEN_DOM0 config

[Oleksandr Dmytryshyn <oleksandr.dmytryshyn@xxxxxxxxxxxxxxx>]

Xen hypervisor changes the CPU Frequency using the CPU
Frequency scaling drivers in the kernel Dom0. Thus those
drivers should be visible in the menuconfig in case
kernel Dom0.
