[PATCH] clk: rockchip: Fix error pointer check after rockchip_clk_register_gate_link()

[Alexander Shiyan <eagle.alexander923@gmail.com>]

From: Miaoqian Lin <linmq006@gmail.com>

Replace NULL check with IS_ERR_OR_NULL() check after calling
rockchip_clk_register_gate_link() since this function
returns error pointers (ERR_PTR).
