clk: tegra20: Fix refcount leak in tegra20_clock_init

Browse Source 
[ Upstream commit 4e343bafe03ff68a62f48f8235cf98f2c685468b ]

of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
