Lowering the voltage solves the quick image degradation over time

USB-ID signal has a pullup on the schematic, but in reality it's not
pulled up, so add a GPIO pullup. And we also need a usb0_vbus_power-supply

The issues came from ID pin reading 0, causing host mode to be

Allwinner sun6i, sun8i, sun9i, and sun50i SoCs contain a hardware
message box used for communication between the ARM CPUs and the ARISC
management coprocessor. This mailbox contains 8 unidirectional
4-message FIFOs.
Add a driver for it, so it can be used with the Linux mailbox framework.
This mailbox hardware is present in Allwinner sun6i, sun8i, sun9i, and
sun50i SoCs. Add a device tree binding for it.

Missing parts are eink display driver and the touch panel driver.
Support for both is available out-of-tree for now at:

The rest of the board is supported by the mainline drivers.

Makes sense. A lot of camera sensors run their digital parts off 1.8V.
