====================
phy: micrel: fix issues with interrupt on atmel boards

Since the phy is not polled anymore, there were issues getting a link on the
sama5d* xplained boards.

I'm not too sure about were those fixes should go and I'm wondering whether the
first one shoud be made generic.

For the second one, I found the PHY_HAS_MAGICANEG flag that is not used and I
wondering whether this is related to that kind of issue. I had a quick look at
the history and could'nt find its use.
