====================
net-next: Broadcom PHY driver cleanup

I will probably need to use broadcom.ko for PHY connected to interface
of bgmac supported device so I started looking at it willing to
understand it better.

I found AUXCTL part of the driver / lib a bit confusing and hard to read
so I'm trying to clean it up a bit. I hope this patchset makes following
AUXCTL operations much easier making it clear which defines are for
registers and which for values.

There is no functional change in this pachset.
