Add device tree files for Agilex SoC platform.

Based on Linux Commit ID 4b36daf9ada30.

Signed-off-by: Ley Foon Tan ley.foon.tan@intel.com

--- v5: - Add CCU DT node.

v4: - Add u-boot,dm-pre-reloc to sysmgr node.

v3: - Fixed bank 1 memory alias base address to 0x280000000. - Rename STRATIX10_*_CLK to SOCFPGA_SOC64_*_CLK. - Include socfpga-soc64-clock.h - Change to "intel,sdr-ctl-agilex" for SDRAM node.

v2: - Add clock property to device node. - Change memory size to 8GB - Enable i2c1 --- arch/arm/dts/Makefile | 1 + arch/arm/dts/socfpga_agilex.dtsi | 500 ++++++++++++++++++ arch/arm/dts/socfpga_agilex_socdk-u-boot.dtsi | 79 +++ arch/arm/dts/socfpga_agilex_socdk.dts | 136 +++++ 4 files changed, 716 insertions(+) create mode 100644 arch/arm/dts/socfpga_agilex.dtsi create mode 100644 arch/arm/dts/socfpga_agilex_socdk-u-boot.dtsi create mode 100644 arch/arm/dts/socfpga_agilex_socdk.dts
