[PATCH AUTOSEL 6.10 25/70] clk: bcm: bcm53573: fix OF node leak in init

[ Upstream commit f92d67e23b8caa81f6322a2bad1d633b00ca000e ]

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().
