I was kinda hoping to drop these all together for 15, but need to do more research into whether or not that's safe to do...
at least all but the last two lines.
This change, though, is good

I think we still want the unit wiring for UARTs so uart0 is reliably COM1, etc. I'm less certain if we can reliably drop the "fixed" devices (attimer, atrtc, atkbdc) as ACPI tables have inconsistently enumerated them over the years. It maybe that we could drop the fixed devices for amd64. The 'sc' hints are tied to when we decide to deprecate sc(4) and only support vt(4) I think.
