KVM: PPC: Book3S HV: Implement virtual mode H_PAGE_INIT handler
Implement a virtual mode handler for the H_CALL H_PAGE_INIT which can be
used to zero or copy a guest page. The page is defined to be 4k and must
be 4k aligned.
The in-kernel handler halves the time to handle this H_CALL compared to
handling it in userspace for a radix guest.
