drm/mediatek: Fix device node reference leak in mtk_dp_dt_parse()

Browse source

The function mtk_dp_dt_parse() calls of_graph_get_endpoint_by_regs()
to get the endpoint device node, but fails to call of_node_put() to release
the reference when the function returns. This results in a device node
reference leak.

Fix this by adding the missing of_node_put() call before returning from
the function.

Found via static analysis and code review.
