Basic example main executiont.

Brings up the full JESD204 link between the FPGA and the ADRV903X:

1. AD9528 clock synthesizer setup (DEVCLK + SYSREF)
2. SYSREF_REQ GPIO configuration
3. ADXCVR initialization (TX and RX)
4. AXI JESD204 TX and RX controller initialization
5. ADRV903X initialization (firmware load up to PreMcsInit_NonBroadcast)
6. AXI clkgen setup (lane_rate / 66 for JESD204C)
7. JESD204 topology initialization and FSM start FSM drives: MCS (LINK_SETUP/OPT_SETUP_STAGE1/2) + link enable
8. JESD204 link status readback

Returns

0 on success, negative error code on failure.
