firmware: arm_scmi: Improve checks in the info_get operations

Browse source 
SCMI protocols abstract and expose a number of protocol specific
resources like clocks, sensors and so on. Information about such
specific domain resources are generally exposed via an `info_get`
protocol operation.

Improve the sanity check on these operations where needed.
