target-lm32: make cpu-qom.h not target specific
Browse files Browse the repository at this point in the history
Make LM32CPU an opaque type within cpu-qom.h, and move all definitions of
private methods, as well as all type definitions that require knowledge
of the layout to cpu.h.  This helps making files independent of NEED_CPU_H
if they only need to pass around CPU pointers.
