[PATCH v1 05/20] arm: socfpga: Add handoff data support for SoCFPGA Agilex5 device

[tien.fong.chee at intel.com]

From: Tien Fong Chee <tien.fong.chee at intel.com>

Agilex5 supports both HPS handoff data and DDR handoff data.
Existing HPS handoff functions are restructured to support both existing
devices and Agilex5 device.
