In most cases the safe min and max values of the various PPT tunables are
known for various ASUS ROG (and other) laptop models. We can match the
DMI string for these and expose min/max sysfs points, plus set some sane
default values.
As part of the addition of the min/max and defaults, to reduce the amount
of code copy/paste and introduce some sanity a group of macros were added
specific to the PPT and NV tunables. The code becomes much cleaner and
easier to read.
This makes the PPT functions much more usable and safe.
