haswell: resource allocation

The previous code w.r.t. resource allocation was getting lucky
    based on the way fixed mmio resources on the system were being
    chosen. Namely, PCIEXBAR was the lowest mmio space and the other
    fixed non-standar BARs were above it. The resource allocator would
    then start allocating standard BARs below that.

On top of that other resources were being added when
    dev_ops->set_resources() was being called on the PCI domain. At that
    point the PCI range limit were already picked for where to start
    allocating from.

To ensure we no longer get lucky during resource allocation add the
    fixed resources in the host bridge and add the memory controller
    cacheable memory areas. With those resources added the range limit
    for standard PCI BARs is chosen properly.

Depending on haswell board configurations we may need to adjust and
    pass in the size of physical address space needed for PCI resources
    to the reference code. For the time being the CRBs appear to be OK.

Lastly, remove the SNB workaround for reserving 2MiB at 1GiB and 512MiB.
