It is _not_ using BTINFO_CONSOLE "as a type".  It is passing the value 
BTINFO_CONSOLE (which is 6) to the lookup_bootinfo() routine as the 
value of a parameter whose name is "type".  (As in, which type of data
does the struct btinfo_common contain...)

The routine is searching an array of "struct btinfo_common" entries to 
find an entry whose member named type matches the value of the routine 
argument named type.

The names could easily have been foo and bar.

You can see this (for x86 platforms) in file

	src/sys/arch/x86/x86/x86_machdep.c
