      Description of problem:

          SNO installation using UPI with platform None has worked for a long time but recent changes in the installer break such a use case.

      Version-Release number of selected component (if applicable):

          4.20, 4.19, 4.18

      How reproducible:

          Always

      Steps to Reproduce:

          1. Create an install config with platform none, 1 controlPlane.replicas and no worker nodes.
    2. Proceed with the installation via UPI method.

      Actual results:

          The installer failed with error: FATAL failed to fetch Master Machines: failed to generate asset "Master Machines": this install method does not support Single Node installation on platform none

      Expected results:

          The installation should succeed.
