Fix PicoProbe CMSIS restart of second core (#1689)

For some reason `program ... reset" causes OpenOCD to leave the chip in a
state where the 2nd core does not come up properly, leading to problems in
FreeRTOS and others.

Use a separate reset sequence after programming to work around the issue.

Fixes #1687
