I upgraded my Linux image with the last GSRD realease 14.1.

uname -a : Linux socfpga_cyclone5 3.10.31-ltsi-02861-g801a40f# 1 SMP Sun Feb 22 16:59:00 UTC 2015 armv7l GNU/Linux

My device is detected :

dmesg :

usb 1-1: new full-speed USB device number 3 using dwc2

usb 1-1: New USB device found, idVendor=10c4, idProduct=ea60

usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

usb 1-1: Product: CP2104 USB to UART Bridge Controller

usb 1-1: Manufacturer: Silicon Labs

usb 1-1: SerialNumber: 006FA62E

But it is not add as serial device And never display in /dev, I think that usbcore or usbserial driver is missing.
