[RFC PATCH 1/2] dt-bindings: edac: altera: agilex5: document new edac support

[Dinh Nguyen <dinguyen@kernel.org>]

The Agilex5 EDAC module supports ECC on a few additional peripherals. Along
with support for ocram, ethernet and USB, the Agilex5 EDAC adds support for
SDM QSPI, CRAM SEU and IO96B.

The Agilex5 EDAC also exposes up to 7 named interrupts on the manager
node. global_sbe and global_dbe are aggregate single/double-bit error
interrupts that fan-out through the manager's IRQ domain to the child
peripheral ECCs. The remaining named interrupts are routed directly from
dedicated controllers (IO96B memory controllers and Secure Device Manager)
to the GIC.

v2: add if/then to enforce maxItem of 2 interrupts for older platforms,
    and 7 for Agilex5
    add if/then to enforce interrupt-names as required property for
    Agilex5
    enum altr,socfpga-s10-ecc-manager and altr,socfpga-agilex5-ecc-manager
