Sergey Matyukevich e3c1c6e41e board/orangepi: add basic support for orangepi-zero board
This patch adds basic support for orangepi-zero board.
Board support package includes the following components:

- mainline kernel v4.11
- mainline u-boot v2017.03
- extra kernel config options: spidev, spi nor flash, wifi
- dts patches to enable SPI NOR and spidev

More details about this board are available here:
- http://linux-sunxi.org/Orange_Pi_Zero

Note that at the moment networking is not supported right out of the box.
Ethernet submission to mainline kernel is a work in progress, see the
latest dwmac-sun8i branches at https://github.com/montjoie/linux

On-board SDIO WiFi chip XR819 is supported by off-the-tree wireless
driver available at https://github.com/fifteenhex/xradio

Changes from v1:

* Send patch using proper subject
* Update xr819 kernel dts patch: add compatible property

Subject: [PATCH 1/3] ARM: dts: orange-pi-zero: specify XR819 WiFi chip
interrupts
The orange-pi-zero board has Allwinner XR819 SDIO wifi chip. The board
dts file provides a node enabling mmc1 controller. Together with an
out-of-tree driver https://github.com/fifteenhex/xradio this node
enables using the wifi chip.
This commit specifies XR819 interrupt configuration for the driver.
