Subject: [PATCH v6] asus-wmi: Add support for custom fan curves

Add support for custom fan curves found on some ASUS ROG laptops.

These laptops have the ability to set a custom curve for the CPU
and GPU fans via an ACPI method call. This patch enables this,
additionally enabling custom fan curves per-profile, where profile
here means each of the 3 levels of "throttle_thermal_policy".

The format for input fan curves is
"30:1,49:2,59:3,69:4,79:31,89:49,99:56,109:58"
where each block of "30:1," is one point on the curve, and 30c, 1%
of fan RPM up to 100%. This follows the internal WMI format. This
format was chosen as it is used heavily by pre-existing utilities
that were based on using the acpi_call module. Further, each pair
can be defined as "T[ c:]P[ %,]" resulting in "30c:1%,", "30c1 "
or similar with a max of two chars between values.
