nb/amd/mct_ddr3: Use standard C function calls in mct_ResetDataStruct_D() 

Replace open coded memset() functions with calls to the library function.
The new code also explicitly backs up and restores the data structures
that are preserved across calls to mct_ResetDataStruct_D(), and no longer
relies on structure member order to function correctly.
