The runtime PM operations use the suspend/resume functions
even when CONFIG_PM_SLEEP is not set, but this now fails
for the exynos DRM driver:
exynos_mixer.c:1289:61: error: 'exynos_mixer_resume' undeclared here (not in a function)
SET_RUNTIME_PM_OPS(exynos_mixer_suspend, exynos_mixer_resume, NULL)
This removes the #ifdef and instead marks the functions as
__maybe_unused, which does the right thing in all cases and
also looks nicer.

Dear Inki,
Ping? On 4.5-rc1 this is still broken. Can you apply this for fixes
for current rc-cycle?

However, it seems missing this one.

Everybody gets the #ifdef's wrong, so the __maybe_unused approach is
being used increasingly all over the kernel.
