patch to make camdd protocol aware

This change introduces the concept of the current storage protocol
(SCSI, SATA, NVMe) to camdd. Functional, there are no changes.
Structurally, camdd now determines the protocol of the device, breaks
out the probe function into protocol dependent and independent parts,
and switches on the protocol type to parse the CCB status, setup IOs,
etc.
