Input: stmfts - switch to SYSTEM_SLEEP_/RUNTIME_PM_OPS() and pm_ptr()

SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS() are deprecated as
they require explicit protection against unused function warnings.
The new combination of pm_ptr() and SYSTEM_SLEEP_PM_OPS()/
RUNTIME_PM_OPS() allows the compiler to see the functions,
thus suppressing the warning, but still allowing the unused code to be
removed. Thus also drop the __maybe_unused markings.
