Use new GPIO API to abstract GPIO in various drivers.
Had to do it all at once due to name conflicts with API exposed in libopencm3.
Quite invasive patch! Also precipitated an LED API...

Adjust SGPIO GPDMA trigger slice data to a single clock width pulse. Previously, it was 3 clocks long with a 4 clock period, which *seemed* to address GPDMA data drop-outs at maximum baseband speed (20Msps complex).

Extract SGPIO multi_slice configuration argument into an init-time function, so it doesn't need to be passed each time the SGPIO interface direction is changed.

Bracket SGPIO GPDMA slice configuration with multislice==false test. It only makes sense in single slice mode (until I have a clever idea for doing GPDMA with multiple slices).

Add skip-every-N function to CPLD, where N is controlled by three input pins from the microcontroller.
Updated SGPIO CPLD testbench, as it had fallen a bit out of date.
Add SGPIO API initialization and control of CPLD decimation feature.

Fix clock edge for TX mode. TX data was completely crapped up due to skew on my Jellybean/Lemondrop board. Hopefully, this also applies to Jawbreaker. I'll recheck once I have hardware in-hand.

Moved invariant in sgpio_configure() loop out of loop. Originally, so I could use the value to calculate another invariant.

Consolidated two "deep" SGPIO configuration functions into one, qualified by transceiver mode (RX or TX). 95-ish % of the code was common.
