conf: Detect misconfiguration between disk bus and disk address

This patch detects a misconfiguration between the disk bus type and disk
address type for controller based disk buses (SATA, SCSI, FDC and
IDE). The addresses of these bus types are all managed in common code so
it's possible to decide in common code whether the disk address and bus
type are compatible or not.
