mb/dell/optiplex_9010: Add Dell OptiPlex 9010 SFF support
Based on the autoport. The OptiPlex 9010 comes in four different sizes:
MT, DT, SFF and USFF. Tested on SFF only. The other PCBs are slightly
different, but they are designed with intercompatibility in mind. With
small devicetree overrides it should work on OptiPlex 7010 and other
OptiPlex 9010 variants as well.
