ppc64le architecture suppport/deprecation

[Daniel Sionov]

Hi All,

I’d like to discuss my PR that removes support for the ppc64le architecture in KubeVirt, which is currently neither supported nor tested.

This PR deprecates the Ppc64le field in the architectureConfiguration section of the KubeVirt configuration struct, and removes all remaining code references to this architecture.

Does anyone have any objections to this change?

The key question we should address is: Why was this architecture introduced in the first place if there was no concrete plan to support and maintain it?
