thermal/drivers/qoriq: Remove __maybe_unused notations

The combined usage of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS()
allows the compiler to evaluate if the suspend/resume() functions
are used at build time or are simply dead code.

This allows removing __maybe_unused notations from the suspend/resume()
functions.
