[PATCH v2] accel: habanalabs: pm: use DEFINE_SIMPLE_DEV_OPS for pm struct

use DEFINE_SIMPLE_DEV_PM_OPS for hl_pm_ops,
pm_sleep_ptr() to safely drop the references without
triggering compiler warnings. and add the value of
'.freeze .thaw .poweroff .restore'. if these
address are null, may cause error in s4.
