[POWERPC] spufs: move fault, lscsa_alloc and switch code to spufs module
Currently, part of the spufs code (switch.o, lscsa_alloc.o and fault.o)
is compiled directly into the kernel.
This change moves these components of spufs into the kernel.
The lscsa and switch objects are fairly straightforward to move in.
For the fault.o module, we split the fault-handling code into two
parts: a/p/p/c/spu_fault.c and a/p/p/c/spufs/fault.c. The former is for
the in-kernel spu_handle_mm_fault function, and we move the rest of the
fault-handling code into spufs.
