mb/google/{eve,glados}: Copy channel arrays separately
DqByteMapCh0 and DqByteMapCh1 are declared adjacently in the FSP_M_CONFIG struct, so it is tempting to begin memcpy at the address of the first array and overwrite both of them at once. However, FSP_M_CONFIG is not declared with the packed attribute, so this is not guaranteed to work and is undefined behaviour to boot. It is cleaner and less tricky to copy them independently. The same is true for DqsMapCpu2DramCh0 and DqsMapCpu2DramCh1, so we change those as well.
