platform: generic: Add system suspend test

Browse Source 
When the system-suspend-test property is present in the domain config
node as shown below, implement system suspend with a simple 5 second
delay followed by a WFI. This allows testing system suspend when the
low-level firmware doesn't support it.

  / {
    chosen {
      opensbi-domains {
          compatible = "opensbi,domain,config";
          system-suspend-test;
      };
