ide: add generic ATA/ATAPI disk driver
* Add struct ide_disk_ops containing protocol specific methods. * Add 'struct ide_disk_ops *' to ide_drive_t. * Convert ide-{disk,floppy} drivers to use struct ide_disk_ops. * Merge ide-{disk,floppy} drivers into generic ide-gd driver. While at it: - ide_disk_init_capacity() -> ide_disk_get_capacity() Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
