Couple of main additions :-
1. Support for multiple SMC/HVC transports for SCMI:
Some platforms need to support multiple SCMI instances within
a platform(more commonly in a VM). The same SMC/HVC FID is used with
all the instances. The platform or the hypervisor needs a way to
distinguish among SMC/HVC calls made from different instances.
This change adds support for passing shmem channel address as the
parameters in the SMC/HVC call. The address is split into 4KB-page
and offset for simiplicity.
2. Addition od SCMI v3.2 explicit powercap enable/disable support:
SCMI v3.2 specification introduces support to disable powercapping
as a whole on the desired zones.
This change adds the needed support to the core SCMI powercap protocol,
exposing enable/disable protocol operations and then wiring up the new
operartions in the related powercap framework helpers.
