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.
