boards: arm: Add u-blox EVK-ANNA-B1

Add support for u-blox EVK-ANNA-B1 which uses the nRF52832.

This board is similar to the nRF52dk_nrf52832 with
different pin assignments on the header pins and not having
the debug-in and shield SWD headers.

Tested with blinky, button, and Bluetooth peripheral_hr
Addressed review comments, including SW2
Rebased to pick up new board in test_adc.c - corrected typo
Reverted to sda-pin, scl-pin

+`EVK-ANNA-B1 product page`_.
+

+for a complete list of EVK ANNA-B1 hardware features.
+
+Connections and IOs
+===================
+
+LED
+---
+
+* LED0 (red) = P0.27
+* LED1 (green) = P0.25
+* LED2 (blue) = P0.26
+
+Push buttons
+------------
+
+* BUTTON1 = SW1 = P0.25
+* BUTTON2 = SW2 = P0.24
+
+General information on module pin numbering
+-------------------------------------------
+
+The numbering of the pins on the module and EVK do not follow the GPIO
+numbering on the nRF52832 SoC. Please see the `ANNA-B1 Data Sheet`_ for
+information on how to map ANNA-B1 pins to the pin numbering on the
+nRF52832 SoC.
+
+The reason for this is the u-blox module family concept where different
+modules share the same pinout and can be interchanged.
+
+Programming and Debugging
+*************************
+
+Applications for the ``ubx_evkannab1_nrf52832`` board configuration can be
+built and flashed in the usual way (see :ref:`build_an_application`
+and :ref:`application_run` for more details); however, the standard
+debugging targets are not currently available.
+
+Flashing
+========
+
+Build and flash applications as usual (see
+:ref:`build_an_application` and :ref:`application_run` for more details).
+
+Here is an example for the :ref:`hello_world` application.
+
+Open a terminal program to the USB Serial Port installed when connecting
+the board and listen for output.
+
+Settings: 115200, 8N1, no flow control.
+
+Then build and flash the application in the usual way.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: ubx_evkannab1_nrf52832
+   :goals: build flash
+
+Debugging
+=========
+
+Refer to the :ref:`nordic_segger` page to learn about debugging boards
+containing a Nordic Semiconductor chip with a Segger IC.
+
+
+Testing the LEDs and buttons in the EVK NINA-B11x
+*************************************************
+
+There are 2 samples that allow you to test that the buttons (switches)
+and LEDs on the board are working properly with Zephyr:
+
+.. code-block:: console
+
+   samples/basic/blinky
+   samples/basic/button
+
+You can build and flash the examples to make sure Zephyr is running
+correctly on your board. The button and LED definitions can be found in
+:zephyr_file:`boards/arm/ubx_evkannab1_nrf52832/ubx_evkannab1_nrf52832.dts`.
+
+Note that the buttons on the EVK-ANNA-B1 are marked SW1 and SW2, which
+are named sw0 and sw1 in the dts file.
+Also note that the SW1 button and the green LED are connected on HW level.
