Two more ppc64le errors

[henrywang]

Just found another two different errors on ppc64le machine:

1. ERROR Installing to filesystem: Installing bootloader: Failed to find PReP partition with GUID 9E1A2D38-C612-4316-AA26-8B49521E5A8B on ibm-ic922-12.lab.eng.brq2.redhat.com
2. ERROR Installing to filesystem: Found multiple parent devices /dev/sda and /dev/nvme0n1; not currently supported on rdma-cert-03-lp10.rdma.lab.eng.rdu2.redhat.com

Are you sure that wasn't on a ppc64le machine?

The linked TF run is for ppc64le, not s390x.

Yes, it's for ppc64le.
