The cpu architecture is hardcoded in the code to x86_64, hence when provisioning aarch64 system, we see x86_64 being passed as properties through the provisioning.
It is not clear whether this has an impact.

Always

1. Create an InfraEnv with aarch cpuArchitecture
2. Create a BMH and attempt provisioning
3.
 Check metal3/ironic logs and see the x86_64 property being set
