When using the Loongson-3A4000 machine for serial port debugging,
there is no /dev/ttyUSB* output, which makes the serial port unavailable,
For convenience, we open this configuration.

Please, don't add random stuff to defconfig.
Carry it locally in your config as the device doesn't come with the borad, it's your accessory.

Thanks.

Hi, jiaxun

Thank you for your reply:-)，

PL2303 is a commonly used accessory,

I see that other platforms are turned on by default, so I also enabled it.
