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.
