Add Memory Controller Registers polling to get current DRAM Timings/Frequency (#306) Read the memory controller configuration (instead of just relying on SPD data) to get the actual live settings. Currently supported platforms: * Intel SNB to RPL (Core 2nd Gen to Core 13th Gen) - Desktop only (no Server nor Mobile) * AMD SMR to RPL (Zen to Zen4) - Desktop only (no Server, Mobile nor APU). Individual commits below for archival: * First functions skeleton for reading IMC/ECC Registers * Change directory name from 'chipsets' to 'mch' (Memory Controller Hub) * Add Intel HSW and fix new files encoding * First Intel HSW IMC implementation * Add an option to disable MCH registers polling * Remove old include from Makefiles * Better Makefile and padding fixes * Statically init 'imc' struct to generate string relocation record * Small typos & code fixes * Add IMC support for Intel Core 6/7/8/9th Gen (SKL/KBL/CFL/CML) This is a bit more complex than Haswell and below because MMIO switched to 64-bit with Skylake (lot of) betatesting needed * Add IMC read support for Intel SNB/IVB (2nd/3rd gen Core) * Fix hard-lock on Intel SNB/IVB due to wrong access type on MCHBAR pointer * Move AMD SMN Registers & offsets to a specific header file * Add IMC Read support for AMD Zen/Zen2 CPUs * Change 'IMC' to 'MCH' in Makefiles to match actual mch/ directory * Add IMC Reading support for Intel ADL&RPL CPUs (Core Gen12&13) * Add support for Intel Rocket Lake (Core 11th Gen) and AMD Vermeer * Add IMC reading for AMD Zen4 'Raphael' AM5 CPUs * Various Cleanup #1 Change terminology from Intel-based 'MCH' (Memory Controller Hub) to more universal 'IMC' (Integrated Memory Controller) Integrate imc_type var into imc struct.
