if_ed_isa.c change to support pnp on compaq lte dock

OK.

> The system has a plug-n-play bios that knows about this device:
> 	PNP8160: adding irq mask 0x800
> 	PNP8160: adding io range 0x340-0x35f, size=0x20, align=0x20
> 	pnpbios: handle 21 device ID PNP8160 (6081d041)
> But the ed driver in 5.4-RELEASE doesn't attach to it automatically.

Committed.  This is the best way to add an ID.
