boardid: Add helpers to read sku_id strapping into coreboot tables
On many recent Chrome OS boards, the desire to unite more configurations
under the same image has led to the need of a "SKU ID" that identifies
different configurations of the same board (e.g. with certain optional
components stuffed or not stuffed, or replaced with a comparable
component). This is markedly different from the existing "board ID",
because that is reserved to count "revisions" -- changes made to the
same configuration over time during the development process. This patch
adds support to have a mainboard define this SKU ID and pass it through
the coreboot table like we already have for board IDs.
