Custom power profile

[Atemu]

It is possible to build your own power profile in /sys/class/drm/card0/device/pp_power_profile_mode by using profile 6 ("CUSTOM").

Researching what these values do and setting them as some ordered string like '6 0 0 5 1 0 4 500 4587520 -65536 0' is not a great experience; a GUI like LACT could really shine here with labels, sliders and info hovers.

The format of this file is different between generations, which makes it a bit annoying to parse (currently it does not parse the values themselves), but it should be doable. I'll take a look at it.
