Subject: [PATCH] pmdomain: ti: omap_prm: Fix a reference leak on device
 node

When calling of_parse_phandle_with_args(), the caller is responsible
to call of_node_put() to release the reference of device node.
In omap_prm_domain_attach_dev, it does not release the reference.

Fixes: 58cbff023bfa ("soc: ti: omap-prm: Add basic power domain support")
