ARM: dts: add dts files for Cubieboard4

From: Tyler Baker <[email protected]>

This series adds basic support for the Cubietech Cubieboard4.

The Cubietech Cubieboard4 is a A80 based development board with 2GB DDR3, 8GB eMMC, Micro SD, HDMI, VGA, 3.5mm audio jack. One USB OTG port and four USB 2.0 ports.

The sun9i-a80-optimus device tree[1] has been used to boot this board for some time now, as the two platforms are very similar. But there are differences, so it deserves it's own device tree. I've tested this series on a Cubieboard4[2][3] and can confirm UART, eMMC, and MMC are working properly.

This patch series is based on arm-soc v4.0-rc2.

Changes v1 -> v2:
* Use more descriptive notation for stdout-path

Changes v0 -> v1:
* Corrected typo. a80-cubietruck -> a80-cubieboard4.
* Removed bootargs node.
* Added stdout-path for uart0.
* Removed unneeded newline.

2.1.0

From: Tyler Baker <[email protected]>

Add a Cubietech Cubieboard4 device tree and instruct make to build it. This device tree has been derived from the sun9i-a80-optimus.dts as they are very similar in design[1]. Notably, I2C3 is not used on Cubieboard4 and the LED/PWM definitions will need to be updated in the future.

Add a cubietech vendor prefix, as it is missing. The cubietruck, cubieboard2, and cubieboard all already reference this prefix.
