Most of the machine definition code looks the same between different
machine versions. The new DEFINE_CCW_MACHINE macro makes defining a
new machine easier by inserting standard machine version
definitions. This also makes it possible to propagate values between
machine versions.
The patch is inspired by code from hw/ppc/spapr.c
