Dual clock mode is introduced in link layer to support different
datapath widths on the transport layer than on physical layer.
- Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b
- Device clock : Link clock * input data path width / output datapath width
Supports four clock configurations, single or dual clock mode with or
without external device clock.
The configuration interface reflects the dual clock domain.
Add Qsys IP scripts as well as SDC constraint files for the ADI JESD204
peripherals. This allows them to be instantiated and used on Altera/Intel
platforms.
