[PATCH v2] input: misc: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

[Triet Hoang <triet.hoang.dev@gmail.com>]

Convert deprecated SIMPLE_DEV_PM_OPS
to DEFINE_SIMPLE_DEV_PM_OPS and pm_ptr/pm_sleep_ptr().

This lets us drop the __maybe_unused annotations
from the resume callbacks and reduces kernel size
when CONFIG_PM or CONFIG_PM_SLEEP is disabled.

Changes in v2:
- Use pm_ptr() for pm80x_onkey_pm_ops
- Remove #ifdef CONFIG_PM
