fixed driver lockup at channel 0 RX. The fpga firmware
...
was using the smi address pins to determine which channel can write the complex_fifo.
The read side of the complex fifo is connected to the DREQ pin of the SMI interface on the raspberry.
The address pins on the smi interface are at logic 1 when no transfer is in progress.
This caused a deadlock condition: the SMI address pin is at 1, so the fifo cannot be filled, so the DREQ cannot be asserted and the SMI cannot start reading data.

Changes in IO utils.
...
1. removed pigpio
2. moved to using gpiomem api for gpios
3. using spidev for soft-hard spi
4. updated the other parts of software.
note: tbd changes in the config.txt of spidev.
note: tbd moving out he kernel module to /etc/modules.d to be completely free of sudoing anything

LVDS RX -> FIFO Slacks are borderline - need perform timing analysis on the RX FIFO IO (add pipeline?)
