clk: bcm: bcm53573: fix OF node leak in init

[ Upstream commit f92d67e ]

Driver code is leaking OF node reference from of_get_parent() in
bcm53573_ilp_init().  Usage of of_get_parent() is not needed in the
first place, because the parent node will not be freed while we are
processing given node (triggered by CLK_OF_DECLARE()).  Thus fix the
leak by accessing parent directly, instead of of_get_parent().
