ALSA: hda: cs35l41: Fix build error unused-function

If CONFIG_PM_SLEEP is not set,
make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-, will be failed, like this:

sound/pci/hda/cs35l41_hda.c:583:12: error: ‘cs35l41_runtime_resume’ defined but not used [-Werror=unused-function]
 static int cs35l41_runtime_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~
sound/pci/hda/cs35l41_hda.c:565:12: error: ‘cs35l41_runtime_suspend’ defined but not used [-Werror=unused-function]
 static int cs35l41_runtime_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
make[3]: *** [sound/pci/hda/cs35l41_hda.o] Error 1

commit 2238160b4f05 ("PM: core: Add new *_PM_OPS macros,
deprecate old ones"), add new marco RUNTIME_PM_OPS to fix this unused-function problem.
