rules: Enable USB autosuspend on more USB HID devices

Many servers will be connected to KVMs or include iLO support, and this
is often presented as a set of USB input devices. Enabling autosuspend on
these allows the USB hardware to be powered down, avoiding unnecessary
wakeups and power consumption. The input devices will be self powered, so
there's no risk of losing input events as there would be for real input
devices. The same is true of USB input devices that are built into the
system.
