atkbd: Disable periodic polling by default.
It is one of the few remaining Giant-locked callouts. It would be
good to remove it, not mentioning that polling itself is not good.
If this cause keyboard/mouse freezes on some hardware, please set
loader tunable hw.atkbd.hz=1 as workaround and report the issue.
