[PATCH v2 3/8] swnode: fix device_add_of_node() kernel doc

[Johan Hovold <johan@kernel.org>]

Software nodes added to a device by device_add_software_node() are
always secondary firmware nodes even if they may be stored in the
dev->fwnode pointer.

Fix the kernel doc which incorrectly claims that a software node added
using this interface "could become the primary node".

Also clarify that device_remove_software_node() should only be used to
remove software nodes added by device_add_software_node().

Fixes: e68d0119e328 ("software node: Introduce device_add_software_node()")
