For driver subsystems that are not tightly integrated into the OpenSBI
init sequence, it is not important that the drivers are initialized in
any particular order. By putting all of these drivers in one array, they
can all be initialized with a single pass through the devicetree. This
saves about 10 ms of boot time on HiFive Unmatched.

These drivers were merged on an experimental basis without the RPMI
specification being frozen. As a result, they may not be compatible with
the frozen version of the RPMI protocol. Additionally, their devicetree
bindings have not been reviewed and are subject to change. Warn the user
that these drivers make no compatibility guarantees, and that their
behavior and devicetree bindings may change incompatibly in future
versions of OpenSBI.
