jmcneill 2fab455b80 Add support for the Allwinner A83T (sun8iw6p1) SoC. 
Clocks, GPIO, UART, SD card / eMMC, USB, watchdog, and ethernet are
supported. Note that the A83T contains two clusters of four Cortex-A7
CPUs, and only CPUs in first cluster are started for now.

Tested on a Sinovoip Banana Pi BPI-M3.
