firmware: stratix10-svc: Add support to query Arm Trusted Firmware (ATF) version
Add entry in Stratix10 service layer that allow client to retrieve the ATF
version at runtime, which is useful for system diagnostics, compatibility
checks, and ensuring the correct secure firmware is in use.
The change introduces:
- A new service command definition in the Stratix10 service layer to
initiate the ATF version query.
- A corresponding macro definition in the header file to expose the command
ID for use by other components.
The service layer uses a Secure Monitor Call (SMC) to communicate with the
ATF and retrieve the version string, which can then be logged or validated
by client application.
