Lucas Mateus Castro (alqotel) 962104f044 hw/ppc: moved hcalls that depend on softmmu 
The hypercalls h_enter, h_remove, h_bulk_remove, h_protect, and h_read,
have been moved to spapr_softmmu.c with the functions they depend on. The
functions is_ram_address and push_sregs_to_kvm_pr are not static anymore
as functions on both spapr_hcall.c and spapr_softmmu.c depend on them.
The hypercalls h_resize_hpt_prepare and h_resize_hpt_commit have been
divided, the KVM part stayed in spapr_hcall.c while the softmmu part
was moved to spapr_softmmu.c
