While cpufreq support on armhf is available for a while, if support is compiled
as a kernel module, the corresponding module doesn't autoload by default,
thus frequency scaling is not active upon boot until a user manually load it (or
until /etc/modules is modified to forcibly load it).

While in Trusty cpufreq was built-in on armhf, starting with Utopic we made
support available as a kernel module, making people think that cpufreq was
either broken or missing in their new kernels.

To fix it, revert back that decision and make cpufreq compiled-in again on
armhf.
While there, make an annotation so we won't forget in the future (W+).
Proposing for Vivid.
