northbridge/amd/amdfam10: Increase MMIO hole size to 1GB
On modern mainboards with multiple PCI-e devices and a single
graphics card the default MMIO hole size of 512M is inadequate,
leading to resource-hungry PCI-e devices (such as an external
graphics card) being assigned invalid MMIO ranges. This, in
turn, causes the entire PCI subsystem to become unavailable,
leading to a failure to boot.
TEST: Booted KGPE-D16 with nVidia 7300LE and verified proper
operation of PCI/PCI-e devices, including text mode VGA operation
via the add-on card and its VGA option ROM.
