[PATCH 1/6] hw/mips/gt64xxx: Initialize ISD I/O memory region in DeviceRealize()

[Philippe Mathieu-Daudé]

The ISD I/O region belongs to the TYPE_GT64120_PCI_HOST_BRIDGE,
so initialize it before it is realized, not after.
Rename the region as 'gt64120-isd' so it is clearer to realize
it belongs to the GT64120 in the memory tree view.
