[XBOXVMP] Real OG XBOX NVidia GPU exposes 3 access ranges, so retrieve them.
CORE-19011

Fix a "bug" I introduced in commit 61012eb54.
VideoPortGetAccessRanges() expects the caller to specify at least the
total number of ranges the hardware exposes, otherwise it fails with
ERROR_MORE_DATA. (Tested also with the help of Windows' videoprt.sys.)

On real original XBOX there are three:
```
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation NV2A [XGPU] [10de:02a0] (rev a1)
    Subsystem: Unknown [0000:0000]
    Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 03
    Memory at fd000000 (32-bit, non-prefetchable) [size=16M]
    Memory at f0000000 (32-bit, prefetchable) [size=128M]
    Memory at 00000000 (32-bit, prefetchable) [size=512K]
```

Thanks to Stanislav and Daniel for tests on the real XBOX.
