drm/sun4i: mark PM functions as __maybe_unused

Disabling CONFIG_PM produces a compile time warning when these
functions are not referenced:

drivers/gpu/drm/sun4i/sun6i_mipi_dsi.c:1072:12: error: 'sun6i_dsi_runtime_suspend' defined but not used [-Werror=unused-function]
 static int sun6i_dsi_runtime_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/sun4i/sun6i_mipi_dsi.c:1043:12: error: 'sun6i_dsi_runtime_resume' defined but not used [-Werror=unused-function]
 static int sun6i_dsi_runtime_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~~~
