powerpc/eeh: Initialize EEH address cache earlier
The EEH address cache is currently initialized and populated by a single function: eeh_addr_cache_build(). While the initial population of the cache can only be done once resources are allocated, initialization (just setting up a spinlock) could be done much earlier. So move the initialization step into a separate function and call it from a core_initcall (rather than a subsys initcall). This will allow future work to make use of the cache during boot time PCI scanning.
