Adrian Costina fbb2a0e1a0 de10nano: Add hps_conv_usb_n signal to stabilize UART lines 
Without defining this signal, the UART lines receive garbage data
when no cable is connected to the J4 USB UART port.
The GPIO9 is enabled in the reference base design along with the
4MA CURRENT_STRENGTH constraint on the UART pins
