Andreas Tobler da89fa28c6 Add three new drivers for fan control and temperature reading on the
PowerMac7,2.

- The fcu driver lets us read and write the fan RPMs for all fans in the
  PowerMac7,2. This driver is PowerMac specific.
- The ds1775 is a driver to read the temperature for the drive bay sensor.
- The max6690 is another driver to read temperatures. Here it is used to
  read the inlet, the backside and the U3 heatsink temperature.

An additional driver, the ad7417, will follow later.

Thanks to nwhitehorn for guiding me through this driver development.
