boards/arm: add support for udoo_neo_full_m4 board

The UDOO Neo Full single board computer configuration supports
the following hardware features on the Cortex M4 Core:

+-----------+------------+-------------------------------------+
| Interface | Controller | Driver/Component                    |
+===========+============+=====================================+
| NVIC      | on-chip    | nested vector interrupt controller  |
+-----------+------------+-------------------------------------+
| SYSTICK   | on-chip    | systick                             |
+-----------+------------+-------------------------------------+
| UART      | on-chip    | serial port-polling;                |
|           |            | serial port-interrupt               |
+-----------+------------+-------------------------------------+
| GPIO      | on-chip    | general purpose input/output        |
+-----------+------------+-------------------------------------+

The default configuration can be found in the defconfig file:
boards/arm/udoo_neo_full_m4/udoo_neo_full_m4_defconfig

Other hardware features are not currently supported by the port.

Connections and IOs:

The UDOO Neo Full board was tested with the following pinmux
controller configuration.

+---------------+-----------------+---------------------------+
| Board Name    | SoC Name        | Usage                     |
+===============+=================+===========================+
| J4 RX         | UART5_RX_DATA   | UART Console              |
+---------------+-----------------+---------------------------+
| J4 TX         | UART5_TX_DATA   | UART Console              |
+---------------+-----------------+---------------------------+

The board has been tested with the following samples.
 - samples/hello_world
 - samples/basic/blinky
