Add support to export device operating states, such as laptop placement, platform types and propagate this data to AMD PMF driver for use in actions. To retrieve the device operating states data, SRA sensor support need to be enabled in AMD SFH driver. So add support to enable the SRA sensor. Also, remove explicit assignments to sensor_index enum.
