Detect SCP version incompatibility

There has been a breaking change in the communication protocols used
between the AP cores and the SCP on CSS based platforms like Juno.
This means both the AP Trusted Firmware and SCP firmware must be
updated at the same time.

In case the user forgets to update the SCP ROM firmware, this patch
detects when it still uses the previous version of the communication
protocol. It will then output a comprehensive error message that helps
trouble-shoot the issue.
