hwrng: omap - remove #ifdefery around PM methods
Instead of using #ifdefs let's mark suspend and resume methods as
__maybe_unused which will suppress compiler warnings about them being
unused and provide better compile coverage.
Because SIMPLE_DEV_PM_OPS() produces an empty omap_rng_pm structure in
case of !CONFIG_PM_SLEEP neither omap_rng_suspend nor omap_rng_resume
will end up being referenced and the change will not result in
increasing image size.
