c9917b6108 lib: sbi: Add system_suspend_allowed domain property
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.

17b3776c81 docs: domain_support: Update the DT example
commit 3e2f573e70 ("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.
