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()
