Subject: [PATCH 2/6] arm64: dts: agilex5: Add ECC manager and submodule nodes

From: Niravkumar L Rabara <niravkumarlaxmidas.rabara@...era.com>

Add the ECC manager (eccmgr) node and its associated ECC submodules to the
Agilex5 SoCFPGA device tree. The eccmgr node serves as a logical parent to
group various ECC hardware instances, including those for USB, Ethernet,
OCRAM, IO96B memory controllers, Secure Device Manager (SDM) QSPI, and
Configuration RAM (CRAM) Single Event Upset (SEU) subsystems.
