Add a DTS and defconfig for the Terasic DE0-Nano Development and Education
Board running ORPSoC. This board contains an Altera Cyclone IV FPGA with
support chips and I/O.
The DTS was derived from published versions by Kevin Mehall and Marek
Czerski.

Notable changes:
- Change flash0 to spansion,s25sl064p, due to kernel message
m25p80 spi32766.0: found s25sl064p, expected m25p10
- Use reg-shift instead of regstep for i2c0, due to kernel message
ocores-i2c a0000000.ocores: regstep property deprecated, use reg-shift
