ARM: omap2: Fix reference count leaks in omap_control_init()

Browse source

The of_get_child_by_name() function increments the reference count
of child nodes, causing multiple reference leaks in omap_control_init():

1. scm_conf node never released in normal/error paths
2. clocks node leak when checking existence
3. Missing scm_conf release before np in error paths

Fix these leaks by adding proper of_node_put() calls and separate error
handling.
