Add the Altera SDRAM EDAC bindings and device tree changes to the Altera SoC project. There was a discussion thread on whether this driver should be an mfd driver or just make use of syscon, which is already a mfd. Ultimately, the decision to use a simple syscon interface was reached.[1] [1] https://lkml.org/lkml/2014/7/30/514 Signed-off-by: Thor Thayer <tthayer@opensource.altera.com> Acked-by: Pavel Machek <pavel@denx.de> [dinguyen] cleaned-up commit header and remove version history.
