[PATCH] initialize TCE tables
A fairly recent platform requirement states that the OS must clear the
whole TCE table at setup time, in case firmware left any active
mappings in it. Without this initialization, dynamic bus removes can
fail. Firmware rejects these requests if active mappings still exist
for a slot that has been deallocated by the OS.
