firmware: arm_scmi: Improve checks in the info_get operations
[ Upstream commit 1ecb7d27b1af6705e9a4e94415b4d8cc8cf2fbfb ]
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.
