[PATCH 01/19] dt-bindings: riscv: Add vendorid and archid

[Charlie Jenkins]

vendorid and marchid are required during devicetree parsing to determine
known hardware capabilities. This parsing happens before the whole
system has booted, so only the boot hart is online and able to report
the value of its vendorid and archid.
