Peer Chen, are you sure we don't miss any existing devices by doing
this? Also, what would future nvidia chips look like? AHCI only or
dual mode similar ICHs? If compatible mode is going to be supported &&
there is no switch we can mangle from PCI quirks to put it into AHCI
mode, we might wanna keep PCI_CLASS_STORAGE_IDE assuming compatible mode
interface remains similar.
Thanks.
