c2671bb69f lib: rpmi: Make RPMI drivers as non-experimental
As RPMI v1.0 specification is frozen, disable the
experimental tag for such RPMI drivers.

434add551c lib: utils: Initialize miscellaneous drivers in one pass
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.

8d8cc9507b lib: utils: Mark RPMI drivers as experimental
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.
