Subject: arm: socfpga: Add samtec VIN|ING board

Add support for board based on the popular Altera Cyclone V SoC.
This board has the following properties:
 - 1 GiB of DRAM
 - 1 Gigabit ethernet
 - 1 USB gadget port
 - 1 USB host port with an on-board hub
 - 2 QSPI NORs connected to the Cadence QSPI core
 - Multiple I2C EEPROMs and one I2C temperature sensor
