Add ModeSense page 0x25 (DEC special function control page) (#1412)

* Add ModeSense page 0x25 (DECSpecialFunctionControlPage)

VAXServer 3100 (CPU KA41-E) console firmware issues ModeSense(6)
page 0x25 when probing for disks. A disk won't be recognized if
this returns an error.

The DEC SCSI specification[1], section 8.5 documents this page.
