nodeSelector for targeting nodes on amd64 arch not arm64 for multi arch clusters

[hugoprudente]

Is your feature request related to a problem?/Why is this needed
When deploying the CSI Driver on a Multi Architecture node x86_64 and ARM64 the deployment and daemonSet does not support ARM64 and deploy the pods causing CrashLoopBackOff.

/feature

Describe the solution you'd like in detail
As multi node architectures can be recurrent, adding nodeSelector specific would resolve this issue.

Describe alternatives you've considered
I have considered using affinity, but node selector will be clean as discussing with the aws-fsx-csi-driver team, that I patched too.
