[Linux-parport] Add wch382_2s PCI ID

[Jeff Gustafson]

Hi all,
I purchased a two port PCIe serial board. Linux didn't seem to notice
it. I dug into the parport and tty/serial/8250 and added the PCI ID's.
Now the ports are working just fine. 

I am also sending this patch to the linux-serial list since it touches
files in both locations.

...Jeff
