* ata: added ATADevice::ReadCapacity16()

* ata: don't fail if lba_sector_count is null and lba48_sector_count is not
* scsi_periph: if ReadCapacity() returns 0xffffffff, use ReadCapacity16() instead
* scsi_disk: use a different computation in the struct geometry computation for bigger disks
Tested successfully with a virtual 10TB hard drive.
