KVM: PPC: Add SVCPU to Book3S_32
We need to keep the pointer to the shadow vcpu somewhere accessible from
within really early interrupt code. The best fit I found was the thread
struct, as that resides in an SPRG.
So let's put a pointer to the shadow vcpu in the thread struct and add
an asm-offset so we can find it.
