    mpfs: emmcsd: fix uninitialized value
    
    cppcheck reports the following:
    
    arch/risc-v/src/mpfs/mpfs_emmcsd.c:2375:22: error: Uninitialized variable: 
waitbits [uninitvar]
      while (!(status & (waitbits | MPFS_EMMCSD_SRS12_EINT))
    
    The finding is positive and this patch initializes it to
    zero properly.
