sim: punt WITH_DEVICES & tconfig.h support

No arch is using this anymore, and we want all new ports using the
hardware framework instead.  Punt WITH_DEVICES and the two callbacks
device_io_{read,write}_buffer.

We can also punt the tconfig.h file as no port is using it anymore.
This fixes in-tree builds that get confused by picking up the wrong
one (common/ vs <port>/) caused by commit ae7d0cac8c.

Any port that needs to set up a global define can use their own
sim-main.h file that they must provide regardless.
