clk: at91: keep securam node alive while mapping it
pmc_register_ops() gets an owned reference to the
"atmel,sama5d2-securam" node with of_find_compatible_node(). The
success path dropped that reference before passing the node to
of_iomap(), leaving of_iomap() to consume a node pointer after the caller
had released its reference.
Move of_node_put() after of_iomap() so the node remains referenced for
the mapping operation. The unavailable-node error path already releases
the reference.
