Laszlo Nagy 4026eaa19b ad9081_fmca_ebz: Fix device clocks termination
The device clocks are AC coupled LVDS lines without external termination.
For proper operation internal differential termination must be enabled,
the DQS_BIAS will DC bias the AC coupled signal to VCCO/2 (1.8/2) 0.9V

Laszlo Nagy b1f62f09ac ad9081_fmca_ebz:vcu118: initial version
Use over-writable parameters from the environment.

      e.g.
        make JESD_MODE=64B66B RX_RATE=24.75 TX_RATE=12.375 REF_CLK_RATE=375 RX_JESD_L=4 TX_JESD_L=4
        make JESD_MODE=64B66B RX_RATE=16.22016 TX_RATE=16.22016 REF_CLK_RATE=245.76 RX_JESD_M=8 RX_JESD_L=2 TX_JESD_M=16 TX_JESD_L=4
        make JESD_MODE=8B10B  RX_JESD_L=4 RX_JESD_M=8 TX_JESD_L=4 TX_JESD_M=8
