mb/google/zork: only enable RTD2141 when present
An MST hub is only present on some devices that are configured with a
particular daughterboard indicated by EC fw_config, so add a fw_config
probe that matches the USB daughterboard ID from CBI to only enable it
on devices where present, using variant-specific daughterboard IDs.
BUG=b:185862297
TEST=RTD2141 remains in ACPI tables on a berknip with Dali DB, and is
not present on the same system if probe is changed to enable it
for picasso DB.
BRANCH=zork
