amdmct: Rewrite mct_ResetDataStruct_D to avoid array-bounds warning

The code was intentionally using an offset past the end of the array to
    get the value of the next byte when starting to clear the structure.
    Rewrite it to get the end of the array and then increment the starting
    value.

Fixes warning for GCC 6.2 toolchain update:
    src/northbridge/amd/amdfam10/../amdmct/mct/mct_d.c:3628:27:
    In function 'mct_ResetDataStruct_D':
    error: index 2 denotes an offset greater than size of 'u8[2][4]
    {aka unsigned char[2][4]}' [-Werror=array-bounds]
