Most quirks are applied using a specific board type board_ahci_no*
(e.g. board_ahci_nomsi, board_ahci_noncq), which then sets a flag
representing the specific quirk.
ahci_pci_tbl (which is the table of all supported PCI devices), then
uses that board type for the PCI vendor and device IDs which need to
be quirked.
The ahci_broken_devslp quirk is not implemented in this standard way.
Modify the ahci_broken_devslp quirk to be implemented like the other
quirks. This way, we will not have the same PCI device and vendor ID
scattered over ahci.c. It will simply be defined in a single location.
