ide: fix UDMA/MWDMA/SWDMA masks (v3)
* use 0x00 instead of 0x80 to disable ->{ultra,mwdma,swdma}_mask * add udma_mask field to ide_pci_device_t and use it to initialize ->ultra_mask in aec62xx, cmd64x, pdc202xx_{new,old} and piix drivers * fix UDMA masks to match with chipset specific *_ratemask() (alim15x3, hpt366, serverworks and siimage drivers need UDMA mask filtering method - done in the next patch) v2: * piix: fix cable detection for 82801AA_1 and 82372FB_1 [ Noticed by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ] * cmd64x: use hwif->cds->udma_mask [ Suggested by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ] * aec62xx: fix newly introduced bug - check DMA status not command register [ Noticed by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ] v3: * piix: use hwif->cds->udma_mask [ Suggested by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ] Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
