mainboard/google/reef: add memory SKU id support

While the proto boards didn't have a memory SKU notion the
EVT boards do. Therefore, provide support for selecting the
proper memory SKU information based on the memory id straps.

This works on EVT boards because the pins used for the
strapping weren't used on proto. However, internal pullups
need to be enabled so that proto boards read the correct
id.
