[PATCH 24/36] iio: proximity: cros_ec_mkbp: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

[Jonathan Cameron <jic23@kernel.org>]

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

Using these newer macros allows the compiler to remove the unused
structure and functions when !CONFIG_PM_SLEEP + removes the need to
mark pm functions __maybe_unused.
