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;
};

Only privileged domains should be allowed to suspend the entire
system. Give the root domain this property by default and allow
other domains to be given the property by specifying it in the
DT.

commit 3e2f573e707e ("lib: utils: Disallow non-root domains from adding M-mode regions")
added access permission check in __fdt_parse_region(). With the
existing DT example in the doc OpenSBI won't boot anymore.
Let's update the DT example so that it can work out of the box.

The RISC-V convention for the privilege mode is capital letter, like
'M-mode', instead of 'm-mode'.
