* add card instance to accelerant shared info

Browse Source 
* when TRACE_ATOM is enabled in bios.c, we dump
  each accelerant instance of the AtomBIOS rom
  to disk in /boot/common/cache/tmp/ (next to usb
  hid descriptors in the same file name format)
* these images can be parsed with the AtomDis application
