[PATCH] drm/tegra: mark nvdec PM functions as __maybe_unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

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.

Fixes: e76599df354d ("drm/tegra: Add NVDEC driver")
