target/ppc: add support for hypervisor doorbells on book3s CPUs
The hypervisor doorbells are used by skiboot and Linux on POWER9 processors to wake up secondaries. This adds processor control support to the Server architecture by reusing the Embedded support. They are very similar, only the bits definition of the CPU identifier differ. Still to be done is message broadcast to all threads of the same processor.
