mips: cdmm: Fix refcount leak in mips_cdmm_phys_base

Browse Source 
[ Upstream commit 4528668ca331f7ce5999b7746657b46db5b3b785 ]

The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.

Fixes: 2121aa3e23 ("mips: cdmm: Add mti,mips-cdmm dtb node support")
