Dummycon is used as a fallback conswitchp for vgacon and fbcon
in the VT code, and there are no references to it if all three
are disabled, so just leave it out of the kernel image for
configurations without those.

What about MDA_CONSOLE and STI_CONSOLE. Don't they require this as
fallback?
I did some grepping in the kernel sources and found the answer to this
question. It's still surprising that the other consoles don't use
dummycon. They are never unloaded, it seems.
