tcl/interface/ftdi: fix TRST for Olimex TINY adapters 

According to the research by Eldar, TINY-H adapter has nTRST connected
to ACBUS0 directly via a 100 Ohms series resistor. I think it's safe
to assume the older TINY adapter does the same.

See high-res photos at [1].

This patch should fix issues with JTAG for the case when nTRST is
actually connected but is missing from the config.
