dnn: force floating point literals to be float.

ipuustin · ipuustin · commit c2de5cf735d4 · 2017-08-01T15:02:24.000+03:00
In OpenCL code in activations.cl, make the type of floating point
literals to be float. Otherwise the values will be interpreted as
doubles, causing Beignet to have type conversion issues.
