[PATCH RFC v3 2/9] dt-bindings: board: Introduce board-id

[Elliot Berman <quic_eberman@quicinc.com>]

Device manufcturers frequently ship multiple boards or SKUs under a
single softwre package. These software packages ship multiple devicetree
blobs and require some mechanims to pick the correct DTB for the boards
that use the software package. This patch introduces a common language
for adding board identifiers to devicetrees.
