From the ICH5/5R datasheet, the registers are the same for 82801EB and ER,
and 82801EB is already using artisea_chip_map().

Note that I didn't commit this part, I assumed it was a left over from an
attempt to make it work with piixide_chip_map instead of artisea_chip_map

The parallel IDE controller on the ICH5/5R are identical (and use the
same device ID).
