[OpenBIOS] Fix double nvram entry on newworld

[Amadeusz Sławiński]

Fix double nvram entry on newworld

There are two nvram entries on newworld (for example qemu -M mac99)

The first one (nvram at fff04000) has initialized .properties while the
other one has words.

0 > dev / ls
...
fff75e24 pci at f2000000
fff77848 nvram at fff04000
fff778e0 nvram
 ok
0 > dev /nvram at fff04000  ok
0 > words
 ok
0 > .properties
name                      "nvram"
#bytes                    2000
reg                       fff04000   00004000
device_type               "nvram"
compatible                "nvram,flash"
 ok
0 > dev /nvram at 0  ok
0 > words close open seek write read size
 ok
0 > .properties
name                      "nvram"
 ok

This patch fixes initialization, so only one node is created
containing both .properties and words.

0 > dev / ls
...
fff75e24 pci at f2000000
fff77868 nvram at fff04000
 ok
0 > dev /nvram at fff04000  ok
0 > words close open seek write read size
 ok
0 > .properties
name                      "nvram"
#bytes                    2000
reg                       fff04000   00004000
device_type               "nvram"
compatible                "nvram,flash"
 ok
