typedefs.h generally has target-independent types only (the only
exception is AllwinnerAHCIState; plus FWCfg* and uWireSlave are close
misses).  I thought about adding target-arm/typedefs.h or
hw/arm/typedefs.h, but it seemed weird to do that for one type only.

But yes, we can do that too.  I went this way first just to check how
many files were affected.
