lenovo/x60: Add "IBM ThinkPad Embedded Controller" SMBIOS OEM String 

The Linux thinkpad_acpi.c driver looks for this string while
reading information about the system it is running on.

This commit does not make the module load but it is one of
several things that the module looks for on a ThinkPad.
