    ath79: cleanup and enable uart1 on ELECOM WAB-I1750-PS
    
    Cleanup uart1-related node on ELECOM WAB-I1750-PS and enable it for
    "SERIAL" port on the case.
    
    "SERIAL" port can be used for OpenWrt console by adding the following
    line to /etc/inittab and rebooting:
    
    ttyATH1::askfirst:/usr/libexec/login.sh
