    ramips: lzma-loader: use default uart for rt305x
    
    The rt305x series SOC have two UART devices,
    and the one at bus address 0x500 is disabled by default.
    Some boards do not even have a pinout for the first one,
    so use the same one that the kernel uses at 0xc00 instead.
    
    This allows the lzma-loader printing to be visible
    alongside the kernel log in the same console.
