feat(intel): add FDT support for Altera products
Support FDT for Agilex5 platform
1. Created wrapper file socfpga_dt.c
2. Added in Agilex5 dts file
3. Implemented fdt_check_header
4. Implemented gic configuration
5. Implemented dram configuration
Remove init of FDT as Agilex5 has no plan to roll
out FDT at the moment.
