alim15x3: use ->host_flags and ->udma_mask fields from ide_pci_device_t
* Make a local copy of ali15x3_chipset in alim15x3_init_one() and set ->host_flags / ->udma_mask according to the controller capabilities. * Cleanup init_hwif_common_ali15x3(). * Bump driver version. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
