Subject: [PATCH] spmi: of: Populate fwnode in of_spmi_register_devices

This patch allows the of_devlink feature to work across spmi devices. This
avoid unnecessary probe deferrals of spmi devices, defers consumers of spmi
devices till the spmi devices probe, and allows spmi drivers to implement
sync_state() callbacks.
