nb/intel/sandybridge: increase MMCONF_BASE_ADDRESS 

Set MMCONF_BASE_ADDRESS to 0xf8000000.
It was already done for some boards, but not all.

The sandybridge chipset code assumes 64 pci buses behind MMCONF.
Therefore, only 64MiB of physical address space is required.

Increasing the address allows to use additional 128MiB of MMIO
space and to use the Intel IGD and a PEG at the same time.

Previously it wasn't possible to use both at the same time,
as two 256MiB areas won't fit into MMIO space.

Test system:
 * Gigabyte GA-B75M-D3H
 * Intel Pentium CPU G2130
 * Onboard GPU Intel IvyBridge Desktop
 * PEG GPU AMD RV770
