NanoPi M1 is a board based on Allwinner H3 CPU.
This commit adds the support for this platform with: - a device tree which enables UART, LEDs, GPIO key switch, 3 USB host ports and the SD-card - a defconfig file for minimal support - a section in MAINTAINERS (add myself)
Based on the orangepi-pc and the device tree from the kernel.
