HP ProLiants are sold with CPU frequency controlled by BIOS by default.
The pcc-cpufreq driver still exports some frequency info to userspace and
should be tried to get loaded on these platforms.
Successfully tested on a recent ProLiant machine:
- without this patch no pcc-cpufreq driver loaded, no frequency info
- with this patch the driver got autoloaded

As Rafael picks patches from patchworks, you may need to resend it to
linux-pm, for now I have cc'id it.
