[PATCH] input: keyboard: 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_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.
