2021-01-10cpu/intel/haswell/haswell.h: Align with BroadwellAngel Pons
Sort MSR definitions, move MCHBAR registers to northbridge and relocate C-state latency macros into the header. Tested with BUILD_TIMELESS=1, Asrock B85M Pro4 remains identical.

2020-10-24nb/intel/haswell/finalize.c: Lock down MC ARB registerAngel Pons
The Haswell System Agent BIOS Spec revision 0.6.0 indicates this register needs to be locked, and Broadwell already locks it. Tested on Asrock B85M Pro4, still boots and register is locked.

2020-10-24nb/intel/haswell/finalize.c: Lock PCU DDR PTMAngel Pons
This register has a lock bit. The Haswell System Agent BIOS Spec revision 0.6.0 indicates it needs to be set, thus set it. Note that Broadwell already locks this register. Tested on Asrock B85M Pro4, still boots and register is locked.

2020-10-24nb/intel/haswell: Set up Root Complex topologyAngel Pons
System BIOS must program some of the Root Complex Topology Capability Structure registers located in configuration space, specs say. So do it. Tested on Asrock B85M Pro4, still boots.

2020-10-23nb/intel/haswell/raminit.c: Clean up local variablesAngel Pons
Remove unnecessary arrays, use unsigned types for non-negative values and constify where possible. Also define NUM_CHANNELS and NUM_SLOTS.

2020-10-15nb/intel/haswell: Account for DPR region in memory mapAngel Pons
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.
