[PATCH] ide: fix UDMA/MWDMA/SWDMA masks * 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)
