Subject: [PATCH v2 01/26] arm: socfpga: agilex5: Add new driver model for system manager in Agilex5

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

Initial creation of new system manager driver.

Add supports for the SOCFPGA System Manager Register block which aggregates different peripheral function into one area.
On 64 bit ARM parts, the system manager only can be accessed during
EL3 mode, this driver model provide user the high level access to system register and abstract user from low level access.

The base address of system manager can be retrieved using DT framework through the System Manager driver.
