powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S

Browse Source 
The system call table has been consolidated into systbl.S.  We have
separate 32-bit and 64-bit versions of entry.S and misc.S since the
code is mostly sufficiently different to be not worth merging.
There are some common bits that will be extracted in future.
