Third version of a hwmon driver to monitor the fan's rpm on Microsoft 
Surface devices, originally submitted in [1], v2 at [2]. All changes since
v2 are incorporating feedback, cleaning up and simplifying the module.

Changes in v3:
  - Removed type and attr checks in read and is_visible.
  - Removed assigning sdev to ssam_device drvdata.
  - Propagate return from __ssam_fan_rpm_get.
  - Renamed hwmon chip name from 'fan' to 'surface_fan'.
  - Removed unnecessary platform_device header.
Changes in v2:
  - Removed all unsupported sysfs attributes from the hwmon driver, leaving
    the fan input as the only supported attribute.
