hwmon: (ltc2947) Switch to EXPORT_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

Browse Source 
These newer PM macros allow the compiler to see what code it can remove
if !CONFIG_PM_SLEEP. This allows the removal of __maybe_unused markings
whilst achieving the same result. In this case it also lets the
structure itself be removed.
