Re: [PATCH] arm64: dts: allwinner: add support for Pinebook

Pinebook is a A64-based laptop produced by Pine64, with the following
peripherals:

USB:
- Two external USB ports (one is directly connected to A64's OTG
controller, the other is under a internal hub connected to the host-only
controller.)
- USB HID keyboard and touchpad connected to the internal hub.
- USB UVC camera connected to the internal hub.

Power-related:
- A DC IN jack connected to AXP803's DCIN pin.
- A Li-Polymer battery connected to AXP803's battery pins.

Storage:
- An eMMC by Foresee on the main board (in the product revision of the
main board it's designed to be switchable).
- An external MicroSD card slot.

Display:
- An eDP LCD panel (1366x768) connected via an ANX6345/ANX9807 RGB-eDP
bridge.
- A mini HDMI jack.

Misc:
- A Hall sensor designed to detect the status of lid, connected to GPIO PH10.
- A headphone jack connected to the SoC's internal codec.
- A BMA223 gravity sensor connected to the SoC's I2C1 bus. (Not
supported yet)
- A debug UART port muxed with one of the USB ports, only available on
product revision of the main board.

This commit adds basical support for it, with out-of-tree patches for
display support the laptop can be basically usable.
