ARM: add a kuser_cmpxchg64 user space helper

Some user space applications are designed around the ability to perform
atomic operations on 64 bit values.  Since this is natively possible
only with ARMv6k and above, let's provide a new kuser helper to perform
the operation with kernel supervision on pre ARMv6k hardware.

ARM: kuser: move interface documentation out of the source code

Digging into some assembly file in order to get information about the
kuser helpers is not that convivial.  Let's move that information to
a better formatted file in Documentation/arm/ and improve on it a bit.

Thanks to Dave Martin <dave.martin@linaro.org> for the initial cleanup and
clarifications.
