[OpenBIOS] [PATCH 03/13] SPARC64: fix PCI memory base in host ranges

Previously the address of the PCI memory base in the host ranges property was
offset by pci_mem_base. While technically correct, Linux incorrectly calculates
the start of the Simba window based upon this address.

Change the memory base to APB_MEM_BASE to match a real Ultra 5 which prevents
Linux from outputting warnings about incorrect window sizes.
