nb/intel/haswell: Account for DPR region in memory map
While MRC.bin does not allocate any memory for DPR by default, it can be patched to do so. However, the current northbridge code does not account for DPR and will, among other things, place CBMEM inside it. Even though this may seem like a good thing, it renders TianoCore unable to boot and clashes with Intel TXT support (the reason to enable DPR to begin with). Update memmap.c so that CBMEM top does not fall within DPR. Also, report DPR as reserved, so that OSes know that the DPR memory is not to be used.
