lenovo/t60: 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.
