updating ROCKernels to AMDGPU v0.4.1
Created by: leios
This should update ROCKernels to the latest AMDGPU.
This is necessary because otherwise AMDGPU is pinning CUDA at v 3.9.1 and causing the following build error: https://github.com/JuliaGPU/CUDA.jl/pull/1558
I realized after the update that ROCDevice
is now potentially conflicting with AMDGPU.ROCDevice
.
