ahci,ata_generic: let ata_generic handle new MBP w/ MCP89

Browse source 
For yet unknown reason, MCP89 on MBP 7,1 doesn't work w/ ahci under
linux but the controller doesn't require explicit mode setting and
works fine with ata_generic.  Make ahci ignore the controller on MBP
7,1 and let ata_generic take it for now.

Reported in bko#15923.

NVIDIA is investigating why ahci mode doesn't work.
