Subject: [PATCHv3 3/9] EDAC, altera: Remove platform device from check_deps()

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

In preparation for the Arria10 peripheral ECCs, the
platform device parameter is removed from the check_deps()
functions because it is not needed and makes the Arria10
check_deps() cleaner.
