[v9,04/21] hw/core: Support module-id in numa configuration

Commit Message

From: Zhao Liu <[e-mail]>

Module is a level above the core, thereby supporting numa
configuration on the module level can bring user more numa flexibility.

This is the natural further support for module level.

Add module level support in numa configuration.
