Revert "Pick worksize 256 with Cypress if none is specified."
This reverts commit 482322a4b7add8458bee946ffb247a9a587fc25f.
Worksize 256 was only helpful on cypress with ultra-low memory speeds with old SDKs and the new kernels require higher memory clocks, having the opposite net effect.

OpenCL 1.0 does not have native atomic_add and extremely slow support with atom_add so detect opencl1.0 and use a non-atomic workaround.
