drm/xe/hwmon: expose fan speed

Browse source

Add hwmon support for fan1_input, fan2_input and fan3_input attributes,
which will expose fan speed of respective channels in RPM when supported
by hardware. With this in place we can monitor fan speed using lm-sensors
tool.

v2: Rely on platform checks instead of mailbox error (Aravind, Rodrigo)
v3: Introduce has_fan_control flag (Rodrigo)
