Kalhan Trisal cfa3b24c38 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.
