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
CSSI - CMOS Source Synchronous Interface
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
ADRV9001 interfacing IP supports the following modes on Xilinx devices:

CSSI__1-lane 1 32 160 80 5 DDR 4
CSSI__4-lane 4 8 80 80 10 SDR 2
CSSI__4-lane 4 8 160 80 20 DDR 1
LSSI__1-lane 1 32 983.04 491.52 30.72 DDR 4
LSSI__2-lane 2 16 983.04 491.52 61.44 DDR 2
Columns description:
A - SSI Modes
