drm/i915/hwmon: expose fan speed
Add hwmon support for fan1_input attribute, which will expose fan speed
in RPM. With this in place we can monitor fan speed using lm-sensors tool.
$ sensors
i915-pci-0300
Adapter: PCI adapter
in0: 653.00 mV
fan1: 3833 RPM
power1: N/A (max = 43.00 W)
energy1: 32.02 kJ
v2: Handle overflow, add mutex protection and ABI documentation
Aesthetic adjustments (Riana)
v3: Change rotations data type, ABI date and version
v4: Fix wakeref leak
Drop switch case and simplify hwm_fan_xx() (Andi)
v5: Rework time calculation, aesthetic adjustments (Andy)
v6: Drop redundant overflow logic (Andy)
Split fan_input_read() into dedicated helper (Badal)
v7: Fix undefined reference to __udivdi3 for i386 (Andy)
