Changes:

• Added autodetection of Arco Computer Products AC-1075 / AC-1070 controllers to XTIDECFG. These are MCA bus controllers and probably rare as hens teeth but apparently compatible with XUB as one person has confirmed using an AC-1075 as a regular 16-bit IDE controller. The port ranges used by these controllers are not used by anything else according to RBIL so autodetection should be fairly safe.
