ide_pci_generic: add quirk for Netcell ATA RAID
commit c339dfdd65b52bfd947ab29d1210314a2f6d622d upstream.
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:
commit 942dcd85bf8edf38cdc3745306ca250684d99a61
("ide: idedisk_supports_lba48() -> ata_id_lba48_enabled()")
and
commit 4b58f17d7c45a8e5f4acda641bec388398b9c0fa
("ide: ide_id_has_flush_cache() -> ata_id_flush_enabled()")
