fpga: e320: Connect CTRL_IN pins to FPGA
These pins control hardware-controlled fast-lock for tuning or cycle-accurate gain control. This commit does nothing to these pins other than expose them into the design and assign them to zero. This does not change the current behaviour (the motherboard has pull-downs on these pins, so they're low by default).
