[PATCH v5 2/2] ARM: dts: sun7i: Add Merrii A20 Hummingbird board

[wills.wang.open@gmail.com (Wills Wang)]

This adds support for the A20 Hummingbird:
http://www.merrii.com/en/pla_d.asp?id=171

This patch enable most on-board peripherals supported on current kernel,
such as uart, i2c, spi, pwm, ohci/ehci, gmac and mmc.
