nb/intel/sandybridge: Drop `pci_mmio_size`

There's no good reason to use values smaller than 2 GiB here. Well, it
increases available DRAM in 32-bit space. However, as this is a 64-bit
platform, it's highly unlikely that 32-bit limitations would cause any
issues anymore. It's more likely to have the allocator give up because
memory-mapped resources in 32-bit space don't fit within the specified
MMIO size, which can easily occur when using a discrete graphics card.
