mb/lenovo/t60: Add support for ThinkLight

With this patch, the ThinkLight on the ThinkPad T60 can be controlled
through the OS. This was initially done for the X201 in f63fbdb6:
mb/lenovo/x201: 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
