ide_pci_generic: add quirk for Netcell ATA RAID
We need to explicitly mark words 85-87 as valid ones since firmware doesn't do it. This should fix support for LBA48 and FLUSH CACHE [EXT] command which stopped working after we applied more strict checking of identify words in: commit942dcd85bf
("ide: idedisk_supports_lba48() -> ata_id_lba48_enabled()") and commit4b58f17d7c
("ide: ide_id_has_flush_cache() -> ata_id_flush_enabled()") Reported-and-tested-by: "Trevor Hemsley" <trevor.hemsley@ntlworld.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
