CPU UV: initial adaptation to new sysfs

idk if this is correct since i didn't test it or even compile it yet. it is quite late and i just want to get this over with lol.

anyone please check if the voltages and the check are correct.
init: set balanced performance profile to interactive

pegasusq is a piece of shit. it provides no noticeable performance improvement over abyssplug. change it to interactive governor, which with the new(or maybe old) frequency calculation, scales frequencies SO much better. performance and general ui smoothness is greatly improved.
