srst_pulls_trst is only true on some (broken) LPC2148 boards, a fact
which is already documented in doc/openocd.texi, so it shouldn't be
set unconditionally in the target tcl.

This patch was needed to reflash when an Abort exception occured very
early after reset, before OpenOCD tried to halt the CPU.
