[PATCH 2/7] EDAC, altera: Add register offset for ECC Enable

[<tthayer@opensource.altera.com>]

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

In preparation for the Arria10 peripheral ECCs, a register
offset from the ECC base was added to the private data
structure to index to the ECC enable register.
