Sparse supports named address spaces since v0.6.0-rc1.
This gives much nicer warnings ('... __user' instead of '... <asn:1>')
but this featres is not yet used in the kernel since it could be
a problem for people using an older version of Sparse.
So, add a define which can be used to check if named address spaces
are supported or not.
I should have done this a long time ago!
