Subject:    [PATCHv2 1/7] EDAC, altera: New file operations for Arria10 ECC modules

From: Thor Thayer <tthayer@opensource.altera.com>

In preparation for the Arria10 peripheral ECCs, new file
operations are used because the Arria10 IRQ trigger mechanism
is different than Cyclone5/Arria5 and Arria10 L2 cache.

Add new pointer for file operations function to ecc data
structure and point to current file operations function.
