KVM: ppc: Refactor powerpc.c to relocate 440-specific code
This introduces a set of core-provided hooks. For 440, some of these are implemented by booke.c, with the rest in (the new) 44x.c. Note that these hooks are link-time, not run-time. Since it is not possible to build a single kernel for both e500 and 440 (for example), using function pointers would only add overhead.
