sunxi: Orange Pi R1: Fix USB Ethernet and activate SPI

Browse source 
The USB Ethernet is not working with the patches proposed for upstream,
fix this and activate the SPI node as this board always has a SPI flash.

Both patches are also targeted for upstream kernel 4.16 and 4.17.

Subject: [PATCH] ARM: dts: sun8i: fix USB Ethernet of Orange Pi R1
Orange Pi R1 uses a Realtek RTL8152B USB Ethernet chip, which is easily
seen on the board but not show in the schematics. A regulator for the
power of the RTL8152B chip is hidden, which uses the same pin with the
Wi-Fi regulator on the original Orange Pi Zero.
Add this regulator back to the device tree, and bind it to USB1.
