mb/lenovo/t430s: Add support for ThinkLight

With this patch, the ThinkLight on the ThinkPad T430S can be controlled
through the OS.  The same change was done for the ThinkPad X200 in
b45912f4: mb/lenovo/x200: Add support for ThinkLight

After applying this patch, the light can be controlled like this:

    echo on >/proc/acpi/ibm/light
    echo off >/proc/acpi/ibm/light

Or through sysfs at /sys/class/leds/tpacpi::thinklight

Unfortunately I do not own a T430S to test this.
