Review request for KDE Frameworks.


Repository: solid


Description
-------

The /proc/cpuinfo format is wildly different between architectures, our
current method for scraping data only works on x86.

This patch moves all parsing logic into cpuinfo.cpp and adds a fallback
search that works for arm and arm64 architectures.
