[PATCH v2] input: touchscreen: 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 and suspend callbacks.
Also reduces kernel size when CONFIG_PM
or CONFIG_PM_SLEEP is disabled.

Changes in v2:
- Remove DEFINE_SIMPLE_DEV_PM_OPS, use only EXPORT_SIMPLE_DEV_PM_OPS for ad7879_pm_ops
