i2c: mux: Propagate firmware nodes to channel adapters
Device Tree channel nodes are associated with the adapters created by
i2c-mux, but equivalent firmware-node descriptions are not.
Use generic firmware-node operations for the existing channel lookup
and associate the returned node with the adapter. Do not restrict the
lookup by firmware-node type, so Device Tree, software nodes, and ACPI
descriptions all follow the same property traversal. The existing
acpi_preset_companion() call remains in place for the standard ACPI
channel association.
Keep a separate reference to the node returned by the generic lookup
because acpi_preset_companion() may replace the device's primary
firmware node. Release the saved reference after adapter deletion.
