Input: rmi4 - switch to SYSTEM_SLEEP/RUNTIME_PM_OPS() and pm_ptr()

SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS() are deprecated
as they requires 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 #ifdef guards.

Whilst all 3 sets of callbacks are similar, there are small differences
that make it challenging to use a single pm_dev_ops structure - hence
leave the duplication as it stands.
