The RAID mode entries would be needed if the device indicates RAID class
in that mode, but in plain AHCI mode it should indicate SATA AHCI class
which will get picked up by this catch-all so those entries shouldn't be
needed:
/* Generic, PCI class code for AHCI */
{ PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID,
PCI_CLASS_STORAGE_SATA_AHCI, 0xffffff, board_ahci },
Likely a lot of the existing specific PCI IDs could be removed from the
driver because of this (many likely predate the addition of the
class-based catch-all). The only reason to need a specific entry if the
device uses AHCI class is if it needs special handling or workarounds,
which isn't the case here.
