ahci: implement AHCI_HFLAG_NO_FPDMA_AA and update NV quirks

It turns out different generations of MCPs have differing quirks.

* MCP 65-73 : FPDMA AA broken, lies about PMP support, forgets to report NCQ
* MCP 77-79 : FPDMA AA broken, lies about PMP support
* MCP 89    : FPDMA AA broken

Instead of turngin off FPDMA AA on all NVIDIAs, implement
HFLAG_NO_FPDMA_AA, define additional board IDs and apply necessary
quirks.

This fixes bko#15481 and the list of quirks is verified by Peer Chen.
