EDAC, altera: Handle Arria10 SDRAM child node

Browse Source 
Separate the device match arrays for each platform to prevent CycloneV
matches when calling of_platform_populate() on the Arria10 ECC manager
node.

If the SDRAM is a child node of ECC manager, call probe function via
of_platform_populate().
