The "system partition" and "free space" partition layouts are
defined by the CHRP and LoPAPR specification, and used by
OpenBIOS and SLOF. We can re-use this code for other machines
that use OpenBIOS and SLOF, too. So let's make this code independent
from the MAC NVRAM environment and put it into two proper helper
functions.
