[PATCHv3 4/9] EDAC, altera: Abstract ECC Enable Mask in check_deps()

[tthayer at opensource.altera.com]

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

In preparation for the Arria10 peripheral ECCs, the
ECC Enable mask is used in place of hard coded masks
in the check dependency functions.
