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.

I think you've said to others to send patches with RFC in them when they
aren't to be applied.  I sent this with RFC in, and it still got applied.

This is _really_ unfortunate, as the 0-day builder has been sending me a
stream of build errors over it, and I now have a branch with 9 patches
plus this one in fixing those errors...

And I did say in the comments below the --- that it should be left a few
days for the 0-day builder to run through it and find those errors.

Ho hum.
