Johan Hovold 2058aab4e3 USB: serial: ch341: fix disabled rx timer on older devices 
commit 41ca302a697b64a3dab4676e01d0d11bb184737d upstream.

At least one older CH341 appears to have the RX timer enable bit
inverted so that setting it disables the RX timer and prevents the FIFO
from emptying until it is full.

Only set the RX timer enable bit for devices with version newer than
0x27 (even though this probably affects all pre-0x30 devices).
