nvram: Introduce helper functions for CHRP "system" and "free space" partitions
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.
