mambo: fake NVRAM support
This re-configures the Mambo platform to use the new fake NVRAM
introduced by Jack Miller <jack@codezen.org> in commit:
mambo: Add Fake NVRAM driver
An existing NVRAM file can be loaded by pointing SKIBOOT_NVRAM
environment variable to the file when running Mambo.
If no NVRAM file is provided, the default is set to 256Kb and will be
formatted automatically by Skiboot on boot, e.g.:
[ 0.000975501,5 ] NVRAM: Size is 256 KB
[ 0.002292860,3 ] NVRAM: Partition at offset 0x0 has incorrect 0 length
[ 0.002298792,3 ] NVRAM: Re-initializing (size: 0x00040000)
This has been tested in Mambo, on bare metal Linux, as well as OpenPower
BMC machines.
