[PATCH v1 10/34] arm: socfpga: agilex: Enable system manager driver for Agilex

[alif.zakuan.yuslaimi at altera.com]

From: Alif Zakuan Yuslaimi <alif.zakuan.yuslaimi at altera.com>

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

Enable system manager support for Agilex by probing the
system manager driver to initialize during SPL boot up.
