Hello

The CH348 is an octo serial to USB adapter.
The following patch adds a driver for supporting it.
Since there is no public datasheet, unfortunatly it remains some magic values.

It was tested with a large range of baud from 1200 to 1500000 and used with
success in one of our kernel CI testlab.

Regards
