[ Upstream commit d4486fc3098e176cb4a29fee037216484761f9ca ]
The SDMMC ECC IRQ layout selection uses CONFIG_64BIT to distinguish between
Arria10 and Stratix10 paths.
Detect the SoC once at probe via the device match table (.data) store it in
struct altr_arria10_edac, and use it instead of CONFIG_64BIT.
This keeps the decision correct for every ECC child device (OCRAM, SD/MMC,
etc.) and avoids any runtime compatible lookup.

From: Dinh Nguyen <dinguyen@kernel.org>
[ Upstream commit 9868f5c077dfe0b606331f2e782484f91a5789a5 ]
Anchor the devres group and the devm-managed IRQ requests in altr_portb_setup()
to the actual parent device (device->edac->dev) instead of the embedded struct
device inside the copied per-port altr_edac_device_dev.
This keeps devres_open_group(), devm_request_irq(), devres_remove_group() and
devres_release_group() all referring to the same long-lived device so the
group and the resources allocated inside it are torn down together.
Fixes: 911049845d70 ("EDAC, altera: Add Arria10 SD-MMC EDAC support")
