nb/intel/ironlake: 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.
