Move the Star Labs Byte (Mk II / Mk III) into the ADL grouping under
src/mainboard/starlabs/adl/.
Like StarBook Horizon, model differences live under
src/mainboard/starlabs/adl/variants/ using SKU-style variant directories
to share common configuration. Byte Mk II (ADL) and Byte Mk III (TWL)
share a single "y2" variant directory.
Update MAINBOARD_DIR and CMOS layout handling so binary blob paths and
NVRAM options continue to resolve correctly.
Update the documentation to reflect the new blobs path.
Note that BUILD_TIMELESS ROM hashes change since MAINBOARD_DIR is
embedded in the CBFS config file.
