Laszlo Nagy 6a4b46ebb4 axi_adrv9001: Make Rx2 and Tx2 source synchronous interfaces optional
If the Rx2 and Tx2 SSI are disabled the rx1,tx2 data paths are forced to
R1 mode.

Laszlo Nagy fcb16daf5b axi_adrv9001: Add the option of global clock buffers on 7 series
Using global clock can help placement issues where the logic does not fits in one
clock region.

alin724 f8c82c611d axi_adrv9001: Add support for symbol operation mode on Xilinx devices
Add CMOS support for the interface for the following symbol modes on Xilinx devices:

A              B  C       D                     E       F      G            H
CSSI__1-lane   1  16/8    80(SDR)/160(DDR)      80      -      SDR/DDR      SDR/DDR->4/2(C=16), 2/1(C=8)

Columns description:
A - SSI Modes
B - Data Lanes Per Channel
C - Serialization factor Per data lane
D - Max data lane rate(MHz)
E - Max Clock rate (MHz)
F - Max Sample Rate for I/Q (MHz)
G - Data Type
H - DDS Rate

Laszlo Nagy 08b0d19731 axi_adrv9001: Populate correct ratio of the SSI interface and user interface clocks
Depending on FPGA technology the physical layer uses different
deserialization factors and corresponding clock division factors to
divide the source synchronous interface clock. This must be
exposed to software so it can act on it while setting the DDS rate.

Xilinx CMOS clock ratio - 4
Xilinx LVDS clock ratio - 4
Intel  CMOS clock ratio - 1
