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

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.
