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.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]

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.
