Subject: [PATCH] drm/komeda: mark PM functions as __maybe_unused

Without this, we get a couple of warnings when CONFIG_PM
is disabled:

drivers/gpu/drm/arm/display/komeda/komeda_drv.c:156:12: error: 'komeda_rt_pm_resume' defined but not used [-Werror=unused-function]
static int komeda_rt_pm_resume(struct device *dev)
^~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/arm/display/komeda/komeda_drv.c:149:12: error: 'komeda_rt_pm_suspend' defined but not used [-Werror=unused-function]
static int komeda_rt_pm_suspend(struct device *dev)
^~~~~~~~~~~~~~~~~~~~

Fixes: efb465088518 ("drm/komeda: Add runtime_pm support")
