platform: generic: Add system suspend test
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;
};
