This series extends OpenSBI to provide system-level partitioning where each
logical system-level partition is referred to as OpenSBI domain. The last
patch of this series provides documentation for OpenSBI domain support.

It will be responsibility of OpenSBI platform support to populate OpenSBI
domains based on use-case of platform vendor.

We will be having separate series to extend OpenSBI generic platform so that
OpenSBI generic platform can populate OpenSBI domains from DTB passed by the
previous booting stage which in-turn provides more configurability to the
previous booting stage.

These patches are also available in domains_v1 branch at
https://github.com/avpatel/opensbi.git
