[PATCH] cpsw: fix dt probe for one port ethernet

[Alexander Aring]

Taken from linux-omap mailinglist. See:

http://marc.info/?l=linux-omap&m=138682143215842&w=2

Original commit-msg:

When only one port of the two port is pinned out, then dt probe is failing
because second port phy is not found. fixing this by checking the number of
slaves and breaking the loop.

I think we need this, too. Only compile tested.
