We use value supplied via SPROM, or default 10:90 as fallback.

* [PATCH 4/4] bcma: extract SPROM rev 9 the same way as rev 8

SPROM rev 9 was discovered on 14e4:4331, it seems to have very similar
layout to rev 8 one. Use the same extracting function until we find some
differences.

John, drop this one patch for now, please.

It contains typo and breaks SPROM reading on BCM4331. We have to
understand BCM4331 workaround better. This probably has to be applied
on some specific stage, but we don't know it yet.
