soc/intel/meteorlake: Configure DDR5 Physical channel width to 64
A DDR5 DIMM internally has two channels each of width 32 bit. But the total physical channel width is 64 bit. This is the same fix as be5dc3daa "soc/intel/alderlake: Configure DDR5 Physical channel width to 64" Building with GCC LTO cought this buffer overflow when assigning SPD addresses to a buffer.
