  To: devel, sami.mujawar, leif, ardb+tianocore, Nicola.Mazzucato

From: Nicola Mazzucato <nicola.mazzucato@arm.com>

The SCP-firmware has moved to full support for SCMIv2 which means that
the base protocol can be either compliant with SCMI v1 or v2.

Allow any version between SCMI v1.0 and SCMI v2.0 to be compatible
with the current implementation.
