[PATCH v3] EDAC/altera: Guard SDRAM irq2 retrieval for Arria10 only

[muhammad.nazim.amirul.nazle.asmade at altera.com]

From: Nazim Amirul <muhammad.nazim.amirul.nazle.asmade at altera.com>

Guard the irq2 retrieval with an of_machine_is_compatible() check so
that platform_get_irq(pdev, 1) is only called on Arria10 platforms.

Signed-off-by: Nazim Amirul <muhammad.nazim.amirul.nazle.asmade at altera.com>

v3: Fix commit header formatting to follow EDAC/altera: prefix
    convention as per maintainer feedback.
v2: Move irq2 = platform_get_irq(pdev, 1) inside the existing
    of_machine_is_compatible("altr,socfpga-arria10") block instead of
    adding a separate duplicate guard around it.
