Various USB Debug Port fixes (trivial).
- Drop unused DBGP_DEFAULT #defines on boards with chipsets where no
USB Debug Port support is implemented anyway (at the moment, at least):
- hp/dl145_g3
- hp/dl165_g6_fam10
- ICH7: Move unrelated code out of set_debug_port(). All ICH southbridges
with Debug Port hardcode the physical USB port used as Debug Port to 1.
In other words, this port is not user-configurable (as seems to be
the case on NVIDIA MCP55). For now we keep the 'port' parameter in order
to not change the API, this might be fixed differently later.
