Sylvain Munaut 60f664fba3 gateware: Rework the low-level line state monitoring ticks ... The 'tick' system was meant to allow the firmware to monitor the low level state of the line, beyong just "not aligned", but it was never really useful in the present state. Now we have more tick source available (but only one can be measured at the same time). More specifically, the firmware can monitor the presence/absence of raw pulses (LOS condition), it can also monitor the number of '1' pulses to detect an AIS signals, or simply the rate of RX pulses (to tune the local oscillator to incoming signal rate).
