Add ZCU104 board support

[AbdelkadirChantar]

This PR introduces support for the ZCU104 board as a host platform for the Cheshire prototype.

Main actions:

• Define ZCU104 as a new board with its relevent IPs.
• Add ZCU104-specific board parameters.
• Provide ZCU104 compatible implementations for Clock Wizard and DDR4 block IPs.
• Modify the top-level design to target the ZCU104 DDR4 interface.
• Define the ZCU104 DDR4 PHY in the physical definitions.
• Update DRAM instantiation to align with the DDR4 IP implementation.
• Add ZCU104 constraints file to define timing constraints and pin mappings.
• Add ZCU104-specific device tree.
• Add OpenOCD script for ZCU104.

Verification:

• The flow has been tested and successfully synthesized, implemented, and generates a valid bitstream.
• Linux boots successfully on the ZCU104 board with this setup.
