    ramips: mt7620: eMMC: fix compiler warnings in non-debug mode
    
    drivers/mmc/host/mtk-mmc/dbg.c:51:13: warning: 'cmd_buf' defined but not used [-Wunused-variable]
     static char cmd_buf[256];
                 ^~~~~~~
    
    In addition, msdc_reg[] is completely unused, even in debug
    mode.
