hmc6352: add driver for the HMC6352 compass
This driver will report the heading values in degrees to the sysfs
interface. The values returned are headings . e.g. 245.6
Alan: Cleanups requested now all folded in and a sysfs description to keep
Andrew happy. The sysfs description now resembles hwmon.
