firmware: arm_scmi: Refactor device create/destroy helpers
Refactor SCMI device create/destroy helpers: it is now possible to ask
for the creation of all the currently requested devices for a whole
protocol, not only for the creation of a single well-defined device.
While at that, re-instate uniqueness checks on the creation of SCMI
SystemPower devices.
