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

The patch has gone through a few revisions as others tested it and
requested bahaviour changes or reported issues. V4 should be considered
finalised for now and I won't submit a new version until V4 has been
reviewed.

- V1
  + Initial patch work
- V2
  + Don't fail and remove wmi driver if error from
    asus_wmi_evaluate_method_buf() if error is -ENODEV
- V3
  + Store the "default" fan curves
  + Call throttle_thermal_policy_write() if a curve is erased to ensure
    that the factory default for a profile is applied again
- V4
  + Do not apply default curves by default. Testers have found that the
    default curves don't quite match actual no-curve behaviours
  + Add method to enable/disable curves for each profile
- V5
  + Remove an unrequired function left over from previous iterations
  + Ensure default curves are applied if user writes " " to a curve path
  + Rename "active_fan_curve_profiles" to "enabled_fan_curve_profiles" to
    better reflect the behavious of this setting
  + Move throttle_thermal_policy_write_*pu_curves() and rename to
    fan_curve_*pu_write()
  + Merge fan_curve_check_valid() and fan_curve_write()
  + Remove some leftover debug statements
  + Remove '\n' causing double-up of '\n\n'
