[PATCH 2/4] EDAC/altera: use flag to differentiate 64-bit platforms

[Dinh Nguyen <dinguyen@kernel.org>]

In commit (d4486fc3098e "EDAC/altera: Use ECC manager compatible to select
A10/S10 IRQ layout"), it added a way to only differentiate Stratix10 from a
32-bit platform. In preparation to add support for Agilex5, it needs a way to
make a further differentiation.

Make use of the driver match data to hold a flag for different platforms,
specifically Stratix10 and Agilex5.
