This series adds RPMI and SBI MPXY support for OpenSBI. The RPMI service
groups supported include system reset, system suspend, HSM, CPPC, and
clock. The RPMI clock serivice group is exposed to supervisor software
as an MPXY channel.

These patches can also be found in the rpmi_mpxy_v1 branch at:
https://github.com/avpatel/opensbi.git

To test these patches, use the dev-upstream branch of following repos:
* https://github.com/ventanamicro/qemu.git
* https://github.com/ventanamicro/linux.git

To enable QEMU RPMI emulation (using librpmi), use "virt,rpmi=on" as
the QEMU machine name.
