platform/x86: lenovo-wmi-other: Add HWMON for fan reporting/tuning
Register an HWMON device for fan reporting/tuning according to
Capability Data 00 (capdata00) and Fan Test Data (capdata_fan) provided
by lenovo-wmi-capdata. The corresponding HWMON nodes are:
- fanX_div: internal RPM divisor
- fanX_input: current RPM
- fanX_max: maximum RPM
- fanX_min: minimum RPM
- fanX_target: target RPM (tunable, 0=auto)
Information from capdata00 and capdata_fan are used to control the
visibility and constraints of HWMON attributes. Fan info from capdata00
is collected on bind, while fan info from capdata_fan is collected in a
callback. Once all fan info is collected, register the HWMON device.
