[PATCH v4 1/9] firmware: arm_scmi: Set generated device fwnode with platform helpers

[Sudeep Holla <sudeep.holla@kernel.org>]

The SCMI transport probe helper creates a platform device for the SCMI
core. device_set_of_node_from_dev() propagates the supplier's OF node,
but leaves generated devices for non-DT transports without a firmware
node.

Use platform_device_set_of_node_from_dev() for devicetree suppliers so
the shared OF node is referenced and marked as reused. For all other
suppliers, use platform_device_set_fwnode() so ACPI and other firmware
nodes are propagated with a reference that platform_device_release()
can balance.
