Possible bug in Armada-37xx pincontroller

Hi,

After some review of a current Armada 37xx design, we stumbled upon
some pin numbering, which seems doubly-defined, and doesn't seem to
follow the documentation available to us.

We haven't gotten our hardware yet, so we haven't been able to test
it, but the following patch is as we believe it should be defined.

Best regards,
