arm: socfpga: Add USB and UDC support for Cyclone V DK

Add support for USB host mode and USB device mode for the
Cyclone V development kit and enable support for UMS (to
export SD card as USB mass storage). The UMS is activated
via 'ums 0 mmc 0' command, the system must be connected to
a host PC via HPS USB port and SD card must be installed
for this to work.
