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. The use of 3 defines for the serial number template seems odd but it's done in a way that eliminates magic numbers, yet avoids use of strcpy, strlen, strindex, strchr, or strspan: we can have some correctness assured at compile time. Also, the defines can be copy/pasted for other mainboards and we should void errors due to people not changing magic numbers.
