ARM32 SoCFPGAs had separate IRQs for SDRAM. ARM64 SoCFPGAs
send all DBEs to SError so filtering by source is necessary.

The Stratix10 SDRAM ECC is a better match with the generic
Altera peripheral ECC framework because the linked list can
be searched to find the ECC block offset and printout
the DBE Address.
