[PATCH 2/2] ARM: dts: socfpga: Add support for Terasic DE1-SOC board

[Florian Vaussard <florian.vaussard@xxxxxxxxx>]

Compared to Terasic SoCKit, here are some of the notable differences
on the HPS side:
- Only 1 user LED and 1 user KEY
- The QSPI Flash is not populated
- The ADXL345 accelerometer is on I2C0 instead of I2C1

Tested to be working:
- LED / KEY
- Ethernet
- Both USB Host ports
- SD card
- ADXL345 accelerometer
