we had problems in the past where a vendor would have a southbridge
with IDE but add a different chip for IDE. So you had to know whether
to enable the SB ide or the other IDE. I've seen this several times.

CONFIG_IDE kind of fails for this purpose because there might be
multiple parts on the board with IDE and you will end up compiling
them all in. It's going to enable anything that has an IDE and has
this conditional compilation, even if there is a conflict, I think.
But we might need that i82801ca_ide code just so we can disable IDE!
That happens too ...

I think this should be a -y and I think CONFIG_IDE should die. If we
need conditional inclusion of this code, why not
CONFIG_SOUTHBRIDGE_INTEL_I82801ER_IDE? But CONFIG_IDE was really for
the now-removed IDE streams, and it has been incorrectly used for a
different purpose.
