This adds support for the Ainol AW1, an A20-based 7" tablet from Ainol.

The following board-specific features are supported:
* LCD panel
* Backlight
* USB OTG
* Buttons
* Touchscreen (doesn't work without non-free firmware)
* Accelerometer
* Battery

The following are untested:
* Audio output
* Audio speakers
* USB via SPCI connector

The following are not supported:
* Wi-Fi
* Bluetooth
* NAND
* Audio via SPCI connector
* Audio via Bluetooth I2S
