ARM: OMAP2+: Fix refcount leak in omapdss_init_of
omapdss_find_dss_of_node() calls of_find_compatible_node() to get device
node. of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() in later error path and normal path.
Fixes: e0c827aca0730 ("drm/omap: Populate DSS children in omapdss driver")
