The configuration and control setup introduced in commit "extend the
driver for 91c94 and 91c96 support" suffers from a typo defect, which
makes the commit broken.

The typo happens to be in barebox tree, while it's not in the tested
patches I had, and there was a mismatch in my former submission, which
is fixed by this patch.
