Remove need for saturating addition in Neon convolution kernels

Some Neon convolution kernels need saturating addition to maintain
the necessary level of precision given some large filter values. The
need for saturating addition can be removed by halving all of the
filter values (which are all even) prior to executing a convolution
kernel. This patch removes saturating addition from a number of Neon
kernels and modifies the filter values passed in accordingly.
