Hi all,

It's been a busy week, but I finally finished v2.

The biggest change since v1 is Patch 08/10, which now uses custom HWMON
attributes.

As always thank you for your feedback and reviews :)

PD: I lost my changelog so I apologize if I missed something bellow.

Changes since v1:

[03/10]
  - Minor correction in commit message

[04/10]
  - Dropped overflow approach in favor of checking a hardcoded limit for
    device resources

[07/10]
  - Dropped status cache
  - As Armin pointed out, operation 0x01 of GetFanSensors gives us the
    count of temperature sensors related to a given fan. Use this to
    retrieve related sensors for each fan into a bitmap and expose this
    information through pwm*_auto_channels_temp attributes
  - Use related temperature sensors to assign labels to fans
  - Store available fan IDs in a bitmap for convenience

[08/10]
  - Use custom attributes to expose pwm_boost
  - Add pm_ops because if a user sets pwm_boost fans would remain *on*
    after suspending

[10/10]
  - Correct information about GetFanSensors method, based on Armin's
    feedback
