[PATCH 18/18] hwmon: (ina3221) Use DEFINE_RUNTIME_DEV_PM_OPS() and pm_ptr()

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

These new macros allow the compiler to see all the functions even if
!CONFIG_PM* and remove the structures and functions if unused.
This removes the need for __maybe_unused markings.
