[ARM PATCH] 1932/1: fix comment about cache handling syscall

Patch from Nicolas Pitre

Let's make it coherent with what the actual code is doing and has
always done, even in 2.4.  Nobody complained about this so let's
just fix the comment.  The most natural usage pattern for this is
a base address and a size so it's more efficient to have an exclusive
end address anyway.
