Disable MIGraphX composable kernels in Jenkinsfile

[pabloantoniom]

Motivation

We are having issues at MIGraphX stage in nightly runs:

https://ml-ci-internal.amd.com/job/MLIR/job/mlir-nightly-all/2332/pipeline-overview/?selected-node=2505

The issue is in docker login:

echo ****
docker login -u **** --password-stdin
Error saving credentials: open /home/jenkins/.docker/config.json3036935522: read-only file system
script returned exit code 1

So this PR removes that (no longer necessary). Even after doing that, the build will still fail:

https://ml-ci-internal.amd.com/job/MLIR/job/mlir/job/PR-2268/3/pipeline-overview/

Because of an error in MIGraphX composable kernels. This PR also disables that

Technical Details

• Remove docker login
• Disable MIGraphX composable kernels with -DMIGRAPHX_USE_COMPOSABLEKERNEL=OFF flag.

Test Plan

No new test was added

Test Result

MIGraphX stage should now pass

should we merge this PR? So that official nightly run start passing? Or this PR is a temporary fix so that we can run custom nightly runs on it?

I'm trying to, but I'm having a hard time merging this PR. I keep re-running the CI and then someone merges before me. I also tried running an empty run but I just can't. It still runs the MIGraphX step every time, despite having that stage disabled. I dont know what's wrong
