tcl/target: stm32[fl]4x: document the settings for trace
While reviewing on gerrit the change
https://review.openocd.org/6932/
it get clear that the missing documentation on stm32f4x's code
was triggering errors in the new change.
OpenOCD is currently unable to read traces, but these can be
hopefully be read with some other tool.
Document the settings for enabling trace on stm32[fl]4x.
