This edac Altera driver is very weird... it uses the same compatible
differently depending whether this is 32-bit or 64-bit (e.g. Stratix
10)! On ARMv7 the compatible means for example one IRQ... On ARMv8, we
have two. It's quite a new code (2019 from Intel), not some ancient
legacy, so it should never have been accepted...

Oh, it's not that horrible as it sounds. They actually have different
compatibles for edac driver with these differences (e.g. in interrupts).
They just do not use them and instead check for the basic (common?)
compatible and architecture... Anyway without testing I am not the
person to fix the edac driver.

Ok, This should be fixed properly as you describe, but as a quick hack
it wouldn't be hard to just change the #ifdef to check for CONFIG_64BIT
instead of CONFIG_ARCH_STRATIX10 during the rename of the config
symbol.
