platform: generic: Add system suspend test

2023-02-27T14:20:51+00:00

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; }; Signed-off-by: Andrew Jones Reviewed-by: Anup Patel
