Non Unibus and Non Qbus VAXen: Properly handle the boot ROM device support

Browse Source 
- Previously the Option ROM device (OR) logic improperly used the UNIT
  UNIT_ATT flag to indicate a devices with Option ROM support.  This
  bit has specific meaning to many SCP capabilities while there are
  numerous device specific fields in the UNIT structure which DEVICEs
  can use as needed.
- Enhance SCP SHOW output for Option ROM units to indicate the DEVICE
   which each enabled ROM is related to.

Fixes #1210
