X-Git-Tag: v6.16-rc1~97^2~19^2~1

ARM: dts: vt8500: add DT nodes for the system config ID register

Every VIA/WonderMedia SoC has a 32-bit chip ID register at the
MMIO address 0xd8120000. Add respective device tree nodes to let
the system code access it at runtime for the selection of appropriate
hardware quirks where needed.
