[Xen-devel] [RFC PATCH v3 7/8] cpufreq: make cpufreq low-level drivers visible for CPUFREQ_DRV_OPS config

[Oleksandr Dmytryshyn <oleksandr.dmytryshyn@xxxxxxxxxxxxxxx>]

Low-level cpufreq drivers should depend from CPUFREQ_DRV_OPS
config instead of the CPU_FREQ config in case if we want
to use additional high-level cpufreq driver. This patch
is needed for implementation xen-based high-level cpufreq
driver.
