Subject: [PATCH 1/6] dt-bindings: edac: altera: Document additional ECC instances

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

Add support for Secure Device Manager(SDM) QSPI ECC, IO96B memory
controller ECC and Configuration RAM(CRAM) Single Event Upset(SEU).

Add interrupt-names property and increase interrupts maxItems from 2 to 7
to accommodate additional interrupts.
