[PULL 11/28] hw/arm: Add SPI to Allwinner A10

[Peter Maydell <peter.maydell@linaro.org>]

From: Strahinja Jankovic <strahinjapjankovic@gmail.com>

The Allwinner A10 SPI controller is added to the Allwinner A10
description, so it is available when Cubieboard is emulated.

Update the documentation for Cubieboard to indicate SPI availability.
