[OpenBIOS] new world (qemu -mac99), double nvram entry

[Amadeusz Sławiński]

When looking at qemu -mac99 I noticed that there are two nvram entries in openbios:

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

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

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

0 > dev / ls 
...
fff75e24 pci@f2000000
fff77868 nvram@fff04000
 ok
0 > dev /nvram@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
