Grr, this is why relative include paths are bad news.  It breaks the
localisation of includes.  Okay, I'll add that include back, even
though nothing in arch/arm/vfp will be using it.

I'll leave everything else though... the functions in vfp.h will take
too much time to work out what's required and what isn't, and I don't
have the available bandwidth before I go away to work out what functions
are used and what aren't.
