hw/ppc/ppc405_uc.c: Avoid integer overflows
When performing clock calculations, the ppc405_uc code has several places where it multiplies together two 32-bit variables and assigns the result to a 64-bit variable. This doesn't quite do what is intended because C will compute a 32-bit multiply result. Add casts to ensure we don't truncate the result. (Spotted by Coverity, CID 1005504, 1005505.)
