alpha: move __udiv_qrnnd library function to arch/alpha/lib/
We already had the implementation for __udiv_qrnnd (unsigned divide for
multi-precision arithmetic) as part of the alpha math emulation code.
But you can disable the math emulation code - even if you shouldn't -
and then the MPI code that actually wants this functionality (and is
needed by various crypto functions) will fail to build.
So move the extended-precision divide code to be a regular library
function, just like all the regular division code is. That way ie is
available regardless of math-emulation.
