Subject: [PATCH -next] clk: pm_clock: provide stubs for pm_clk_runtime_suspend/_resume

Add stubs for pm_clk_runtime_suspend() and pm_clk_runtime_resume()
to fix build errors when CONFIG_PM and CONFIG_PM_CLK are not enabled.

Fixes these build errors:

../drivers/clk/qcom/camcc-sc7180.c: In function ‘cam_cc_sc7180_probe’:
../drivers/clk/qcom/camcc-sc7180.c:1672:8: error: implicit declaration of function ‘pm_clk_runtime_resume’; did you mean ‘pm_runtime_resume’? [-Werror=implicit-function-declaration]
  ret = pm_clk_runtime_resume(&pdev->dev);
        ^~~~~~~~~~~~~~~~~~~~~
../drivers/clk/qcom/camcc-sc7180.c:1681:3: error: implicit declaration of function ‘pm_clk_runtime_suspend’; did you mean ‘pm_runtime_suspend’? [-Werror=implicit-function-declaration]
   pm_clk_runtime_suspend(&pdev->dev);
   ^~~~~~~~~~~~~~~~~~~~~~

Fixes: 15d09e830bbc ("clk: qcom: camcc: Add camera clock controller driver for SC7180")
