board: sensry: add starter-kit-board

Add soc support for Sensry's RISCV32 based SY1xx.
Variants of the soc are GBM and GEN1 with the
board support for start kit board, which is
a demo board for both soc variants.

+
+Overview
+********
+
+.. note::
+
+   All software for the Ganymed StarterKit (SK) is experimental and hardware availability
+   is restricted to the participants in the limited sampling program.
+
+The Ganymed board hardware provides support for the Ganymed sy1xx series IoT multicore
+RISC-V SoC with optional sensor level.
+
+Hardware
+********
+
+* 32-Bit RISC-V 1+8-core processor, up to 500MHz
+
+  * 1x Data Acquisition Unit
+  * 8x Data Processing Unit
+  * Event Bus
+  * MicroDMA
+
+* 4096 KB Global SRAM
+* 64 KB Secure SRAM
+* 512 KB Global MRAM
+* 512 KB Secure MRAM
+* CLOCK
+* Peripherals
+
+    * :abbr:`32x GPIO (General Purpose Input Output)`
+    * :abbr:`4x TWIM (I2C-compatible two-wire interface with MicroDMA)`
+    * 4x I2S
+    * :abbr:`7x SPI (Serial Peripheral Interface with MicroDMA)`
+    * :abbr:`3x UART (Universal receiver-transmitter with MicroDMA)`
+    * :abbr:`1x TSN (Time sensitive networking ethernet MAC with MicroDMA)`
+    * 1x CAN-FD
+    * 3x ADC
+* Power section for on-board power generation and power measurement (selectable)
+
+    * USB type-C
+    * external 5V power source
+* 40-pin JTAG connector (compatible to Olimex ARM-JTAG-OCD-H)
+* USB over FTDI (connected to UART0)
+* Header for all I/Os and configuration
+
+* Assembly options for the SoC
+
+  * SY120-GBM - Generic Base Module without top level sensors
+  * SY120-GEN1 - Generic Module type 1 with top level sensors (see below)
+
+The ``ganymed-sk/sy120-gen1`` comes with additional on-board sensors.
+
+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+For more detailed description please refer to `Ganymed StarterKit Board Documentation`_
+
+
+Programming and Testing
+***********************
+
+Building
+========
+
+Applications for the ``ganymed_sk/sy120_gbm`` board can be
+built and flashed in the usual way. See
+:ref:`build_an_application` and :ref:`application_run` for more details on
+building and running.
+
+Building the :zephyr:code-sample:`hello_world` sample:
+
+.. zephyr-app-commands::
+   :tool: west
+   :zephyr-app: samples/hello_world
+   :board: ganymed_sk/sy120_gbm
+   :goals: build
+   :compact:
+
+
+Flashing
+========
+
+Test the Ganymed with a :zephyr:code-sample:`hello_world` sample.
+
+Flash the zephyr image:
+
+.. zephyr-app-commands::
+   :tool: west
+   :zephyr-app: samples/hello_world
+   :goals: flash
+   :west-args: --dev-id /dev/ttyUSB0
+   :compact:
+
+
+Testing
+=======
+
+Then attach a serial console, ex. minicom / picocom / putty; Reset the target.
+The sample output should be:
+
+.. code-block:: console
+
+    Hello World! ganymed_sk/sy120_gbm
