Subject: [PATCH] [loco] Remove unused input_nodes helper (#5972)

* [loco] Remove unused input_nodes helper

This commit removes unused input_nodes helper. This helper is currently
unused, but its presence makes it difficult to decouple loco core from
loco canonical.

Signed-off-by: Jonghyun Park <jh1302.park@samsung.com>

* Remove the implementation
