AMDGPU.jl master is broken on Julia 1.7

[utkarsh530]

Hi, I am trying to get AMDGPU.jl to work with the mentioned GPU. Although I can create ROCArray, things like kernel launches and A\b throws an error. The ] test AMDGPU doesn't pass as well.

Part of this is that device_sleep calls an OCKL intrinsic which requires a ConstantInt argument, instead of an SSA value. The other issues, I don't yet know how to fix.

We no longer support 1.7 and #456 adds routines for A \ b.
