Subject: On sparc64 obtain the initiator ID to be used for SPI HBAs from the
 Open Firmware device tree in order to match what the PROM built-in driver
 uses. This is especially important when netbooting Fujitsu Siemens
 PRIMEPOWER250 as in that case the built-in driver isn't used and the port
 facts PortSCSIID defaults to 0, conflicting with the disk at the same
 address.
