The Allwinner System on Chip families sun4i and above contain
an integrated storage controller for Secure Digital (SD) and
Multi Media Card (MMC) interfaces. This commit adds support
for the Allwinner SD/MMC storage controller with the following
emulated features:
* DMA transfers
* Direct FIFO I/O
* Short/Long format command responses
* Auto-Stop command (CMD12)
* Insert & remove card detection
The following boards are extended with the SD host controller:
* Cubieboard (hw/arm/cubieboard.c)
* Orange Pi PC (hw/arm/orangepi.c)
