Subject: [PATCH 6/7] clk: rockchip: remove redundant checking of device_node

rockchip_clk_of_add_provider is used by sub-clk driver which
already call of_iomap before calling it. If device_node does
not exist, of_iomap returns NULL which will fail to init the
sub-clk driver. So really it's redundant.
