A bug fix:

Fix the ctrl_devport_conf_clear to clear the enable bit.

A simplification:
Dynamically enable ck804s that are found instead of relying on #defines.
Removing an Opteron changes the number of ck804s that are present.

Simple changes to make it easier to compare the factory BIOS with Coreboot when
using SerialICE for boards with the Nvidia ck804 chipset:
If the mask is zero, don't read the value, just write the new value over it.
