hw/arm: add Allwinner H3 System-on-Chip 

The Allwinner H3 is a System on Chip containing four ARM Cortex A7
processor cores. Features and specifications include DDR2/DDR3 memory,
SD/MMC storage cards, 10/100/1000Mbit Ethernet, USB 2.0, HDMI and
various I/O modules. This commit adds support for the Allwinner H3
System on Chip.
