Commit a52c8f52 introduced machine check magic for the RapidIO chip.
Unfortunately it was so magical that it used constants that aren't even
defined!

This patch bluntly comments out the broken constant's usage. This
probably means that said functionality thus doesn't work, but at
least it makes it compile for me.
