Including phy.h and phy_fixed.h into net/dsa.h causes phy*.h to be an
unnecessary dependency for quite a large amount of the kernel.  There's
very little which actually requires definitions from phy.h in net/dsa.h
- the include itself only wants the declaration of a couple of
structures and IFNAMSIZ.

Add linux/if.h for IFNAMSIZ, declarations for the structures, phy.h to
mv88e6xxx.h as it needs it for phy_interface_t, and remove both phy.h
and phy_fixed.h from net/dsa.h.

This patch reduces from around 800 files rebuilt to around 40 - even
with ccache, the time difference is noticable.

Applied, thanks.

Hmm, now that's _really_ interesting.

It got reviewed-by and seemed reasonable.

I am always allowed to use my judgment to turn an RFC into a patch
I actually apply, especially when other developers review the change.

If you read your email now you'll see that I reverted it before
pushing it out, because of the fallout you mention.
