intelblocks/systemagent: Add ACPI table generation hook
In preparation of generating DMAR tables, provide the hook in SoC scope for the systemagent to write ACPI tables. The complete functionality is SoC-specific. Therefore the entry hook is defined as a weak function which can be overridden by SoC code. If the SoC does not have support for generating DMAR tables this hook will do no harm.
