rockchip: add Orange Pi R1 Plus support

Orange Pi R1 Plus is a Rockchip RK3328 based SBC by Xunlong.

This device is similar to the NanoPi R2S, and has a 16MB
SPI NOR (mx25l12805d). The reset button is changed to
directly reset the power supply, another detail is that
both network ports have independent MAC addresses.

Note: booting from SPI is currently unsupported, you have to install
the image on a SD card.
