E.3.2.2 Bus-specific methods for bus nodes
A package implementing the scsi-2 device type shall implement the
following bus-specific method:
set-address ( unit# target# -- )
Sets the SCSI target number (0x0..0xf) and unit number (0..7) to which
subsequent commands apply.

Convert physical address to text unit-string.
Convert phys.lo ... phys-high, the numerical representation, to unit-string,
the text string representation of a physical address within the address
space defined by this device node. The number of cells in the list
phys.lo ... phys.hi is determined by the value of the #address-cells property
of this node.
