serial-dmm: Add Voltcraft VC-840 (UT-D02) support.

This works with the UNI-T UT-D02 (RS232) cable. For the USB/HID
based cable (UNI-T UT-D04), the uni-t-dmm driver must be used.

Note: This is untested, but should work just fine for all settings, with
the possible exception of temperature (testers needed!)
