komeda_rt_pm_suspend() and komeda_rt_pm_resume() are compiled only when
CONFIG_PM is enabled. Having it disabled triggers the following warning
at compile time:

linux/drivers/gpu/drm/arm/display/komeda/komeda_drv.c:156:12:
warning: ‘komeda_rt_pm_resume’ defined but not used [-Wunused-function]
 static int komeda_rt_pm_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~
linux/drivers/gpu/drm/arm/display/komeda/komeda_drv.c:149:12:
warning: ‘komeda_rt_pm_suspend’ defined but not used [-Wunused-function]
 static int komeda_rt_pm_suspend(struct device *dev)

Make komeda_rt_pm_suspend() and komeda_rt_pm_resume() dependent on
CONFIG_PM to address the issue.

Hi Vincenzo:

Thanks for the patch.

and Vincenzo & Liviu, sorry

Since there is a patch for this problem already:
https://patchwork.freedesktop.org/series/71721/

And I have pushed that old fix to drm-misc-fixes just before I saw
this mail. sorry.

No issue, as far as it is fixed :) It is annoying stepping on it during
randconfig :)

Thanks for letting me know!
