    I haven't done a full review of this code, but it I built it in (along
    with other CLs to enable it on exynos5250-snow) and the thermistors
    are accessible and report reasonable values.

    localhost hwmon # grep "" /sys/class/hwmon/*/device/temp1_input
    /sys/class/hwmon/hwmon0/device/temp1_input:37890
    /sys/class/hwmon/hwmon1/device/temp1_input:38393
    /sys/class/hwmon/hwmon2/device/temp1_input:37148
    /sys/class/hwmon/hwmon3/device/temp1_input:38059
