Confirmed that this fixes a bunch of warnings at boot on SC7180 when
(out-of-tree) camera support is enabled:

  [    1.832228] gcc_disp_hf_axi_clk status stuck at 'off'
  [    2.118292] gcc_disp_hf_axi_clk status stuck at 'off'
  [    2.442383] gcc_disp_hf_axi_clk already disabled
  [    2.750054] gcc_disp_hf_axi_clk already unprepared
