TMS570 OpenOCD configuration needs to ensure that POM is disable before reset.

If parameter Overlay Module is not disable before reset,
reset results in hardware fault which can be cleaned
only by PORST (Power on reset).

TMS570 UART test: attempt to keep original reset vector value in POM.

The value is kept but seems to not solve reset lock.
OpenOCD approach in previous commit seems be best solution
for now.
