Daughterboard extension connector CN5 and CN6

Two 60-pin male headers CN5 and CN6 can be used to connect with daughterboard or
standard wrapping board to STM32746G-EVAL evaluation board. All GPIOs are dispatched
on memory connectors (CN10 and CN11), and on connectors CN5 and CN6.
The space between CN5 and CN6 connectors is defined as a standard, this allows
developing common daughterboards for several ST evaluation boards. The standard width
between CN5 pin1 and CN6 pin1 is 2700 mils (68.58 mm).
Each pin on CN5 and on CN6 can be used by a daughterboard, after disconnecting it from
the corresponding function block on STM32746G-EVAL evaluation board. Refer to
