[PATCH 2/2] ide: remove IDE_HFLAG_CY82C693 host flag

[Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>]

Sergei suggested that it shouldn't be necessary + it had no effect
anyway since ide_id_dma_bug() is called earlier in ide_tune_dma().

I went ahead since I urgently needed to re-cycle one host flag.
