Subject: drm/tegra: Mark nvdec PM functions as __maybe_unused
Git-commit: e1189fafa5a1c49407a1bc01d850cc6dd52c058d
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

The resume helper is called conditionally and causes a harmless warning
when stubbed out:

drivers/gpu/drm/tegra/nvdec.c:240:12: error: 'nvdec_runtime_resume' defined but not used [-Werror=unused-function]
  240 | static int nvdec_runtime_resume(struct device *dev)

Mark both suspend and resume as __maybe_unused for consistency to avoid
this warning.
