media: intel-ipu3: cio2: mark more PM functions as __maybe_unused

My earlier patch missed two functions, these must be __maybe_unused
as well:

drivers/media/pci/intel/ipu3/ipu3-cio2.c:1867:12: error: 'cio2_runtime_resume' defined but not used [-Werror=unused-function]
drivers/media/pci/intel/ipu3/ipu3-cio2.c:1849:12: error: 'cio2_runtime_suspend' defined but not used [-Werror=unused-function]

Fixes: 2086dd35 ("media: intel-ipu3: cio2: mark PM functions as __maybe_unused")
