[PATCH] ide: Fix drive's DWORD-IO handling

[Mario Schwalbe]

Resubmitted on request.

According the documentation, id[ATA_ID_DWORD_IO] is non-zero if
the drive supports dword IO, while the code disables support by
setting IDE_DFLAG_NO_IO_32BIT. In addition, this word has been
reused by the ATA8 specification. This patch fixes both cases.
