[RESEND PATCH] ARM: Fix refcount leak in axxia_boot_secondary

[RESEND PATCH] ARM: Fix refcount leak in axxia_boot_secondary

[Miaoqian Lin]

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() to avoid refcount leak.

Fixes: 1d22924e1c4e ("ARM: Add platform support for LSI AXM55xx SoC")
