hw/ppc/spapr: Add missing license

Commit 9fdf0c2995 ("Start implementing pSeries logical partition
machine") added hw/ppc/spapr_hcall.c, then commit 962104f044
("hw/ppc: moved hcalls that depend on softmmu") extracted the
system code to hw/ppc/spapr_softmmu.c. Take the license and
copyrights from the original spapr_hcall.c at commit 9fdf0c2995.
