Versal LP/DDR4 2D Eye Scan

2D Eye Scan support has been added for all integrated Memory Controller interfaces in Versal starting with Vivado 2021.1. A 2D Eye Scan is useful for checking the health of each byte lane and provides a graphical way to compare them, enabling a quick method to look for any layout or board issues. This feature does not require any design changes, and is automatically included in all integrated LP/DDR4 interfaces.
