[PATCH v6 1/9] dt-bindings: gpio: add QIXIS FPGA based GPIO controller

Add a device tree binding for the QIXIS FPGA based GPIO controller.
Depending on the board, the QIXIS FPGA exposes registers which act as a
GPIO controller, each with 8 GPIO lines of fixed direction.

Since each QIXIS FPGA layout has its particularities, add a separate
compatible string for each board/GPIO register combination supported.

Since these GPIO controllers are trivial, make use of the newly added
trivial-gpio.yaml file instead of creating an entirely new one.

Changes in v2:
- Used the newly added trivial-gpio.yaml file
- Removed redundant "bindings" from commit title
- Added only one compatible string for the gpio controllers on
LX2160ARDB since both registers have the same layout.
Changes in v3:
- none
Changes in v4:
- none
Changes in v5:
- none
Changes in v6:
- none
