PWM control circuitry for two fans. The PC87363 chip is similar, and the
PC87364 chip has monitoring and PWM control for a third fan.
The National Semiconductor PC87365 and PC87366 Super I/O chips are complete
hardware monitoring chipsets, not only controling and monitoring three fans,
but also monitoring eleven voltage inputs and two (PC87365) or three
(PC87366) remote temperatures. For now, the driver doesn't handle these
features and treat these two chips as PC87364.
Fan rotation speeds are reported in RPM (revolutions per minute). An alarm
is triggered if the rotation speed has dropped below a programmable limit.
Fan readings can be divided by a programmable divider (1, 2, 4 or 8) to give

Limitations
-----------
This driver is read-only at the moment. Since I don't own a supported
chip for testing, and the datasheet suggests that you shouldn't change
values once the monitoring has started (this is normally done by the BIOS
at boot time), I decided to play it safe.
