Compared to xt_IDLETIMER, xt_HARDIDLETIMER can send notifications when
CPU is in suspend too, to notify the timer expiry.
Would it make sense to add this feature to IDLETIMER instead of a new
module? AFAICS there is a lot of boilerplate overlap between those two.
Its a feature specific module .Keeping it as a separate module helps us
to enable and disable it via defconfig.
As iptable rules are target specific , it also helps iptable rules run
independently and easier to debug .
