tco-test: fix up config accesses and re-enable 

The mistake that made the test fail was that it tried to
use a BAR address as an offset for config accesses to LPC.

Config accesses don't need a BAR, and LPC does not have one. Don't
attempt to map it.

With this change applied, TCO test passes, so re-enable it.
