Provide the model information through sysinfo so that it shows up on
boot. For memconfig 4 pins are provided, for 16 combinations. For SKU
ID there are two options:
- two pins provided in a ternary arrangement, for 9 combinations.
- reading from the EC
Add a binding doc and drop the unused #defines as well.
Example:
