[PATCH 0/3] OpenSBI domain initialization order

Currently, we rely on the "opensbi-domain" DT property of CPU DT nodes
to select the domain assigned to each HART at boot-time but unfortunately
this is only suitable if we have two non-ROOT domains (aka trused and
non-trusted. For more than two non-ROOT domains, the domain initialization
order should be much more predictable where users should define the exact
order via some DT property under domain DT nodes.

These patches can also be found in sbi_domain_init_order_v1 branch
at: https://github.com/avpatel/opensbi.git
