I simply forgot to enable CONFIG_PRINTK_TIME. Here is what the log looks 
like after enabling it.

[    1.886100] nuvoton-dwmac 40120000.ethernet: TX Checksum insertion 
supported
[    1.893104] nuvoton-dwmac 40120000.ethernet: Enhanced/Alternate

[    1.906806] nuvoton-dwmac 40120000.ethernet: Ring mode enabled
