interface/ftdi: add TUMPA Lite config

TUMPA Lite is a cheap FT232H-based breakout board, without any
buffering. It also lacks series resistors so for some targets
(especially when not using ridiculously short wires) one needs to add
about 47 Ohms in series on every high-speed line.

The SRST line is connected directly to the FT232H too.

Real-life tested (including SRST and TRST).
