platform/x86: pcengines-apuv2: wire up simswitch gpio as led
The APU3+ boards have two SIM sockets, while only one of them can be routed to the mpcie slots at a time. Selection is done via simswap gpio. We currently don't have a fitting subsystem for those cases yet, so just wire it up to a LED for the time being. While this isn't really semantically correct, it's a good compromise.
