All Allwinner H616/H618 SoCs contain a Mali G31 MP2 GPU.
Enable the DT nodes for that GPU, and specify the regulator providing
power to the VDD_GPU pins of the package. The rest of the DT node is set
by the SoC, so is not board specific.

With the DT bindings now describing the format of the CPU OPP tables, we
can include the OPP table in each board's .dts file, and specify the CPU
power supply.
This allows to enable DVFS, and get up to 50% of performance benefit in
the highest OPP, or up to 60% power savings in the lowest OPP, compared
to the fixed 1GHz @ 1.0V OPP we are running in by default at the moment.

Documentation/process/license-rules.rst and checkpatch expect the SPDX
identifier syntax for multiple licenses to use capital "OR". Correct it
to keep consistent format and avoid copy-paste issues.

CB1 is Compute Module style board that plugs into Rpi board style adapter or
Manta 3D printer boards (M4P/M8P).
The SoM features:
- H616 SoC
- 1GiB of RAM
- AXP313A PMIC
- RTL8189FTV WiFi
Boards feature:
- 4x USB via USB2 hub (usb1 on SoM).
- SDcard slot for loading images.
- Ethernet port wired to the internal PHY. (100M)
- 2x HDMI 2.0. (Only 1 usable on CB1)
- Power and Status LEDs. (Only Status LED usable on CB1)
- 40 pin GPIO header
Currently working:
- Booting
- USB
- UART
- MMC
- Status LED
- WiFi (RTL8189FS via out of tree driver)
I didnt want to duplicate things so the manta DTS can also be used on BTT pi4b adapter.
CB1 SoM has its own DTSI file in case other boards shows up that accept this SoM.
