Re: [PATCH v2] EDAC/altera: use SDMMC compatibles to select A10/S10 IRQ layout

Thank you for the review.

I originally used the altr,socfpga-s10-sdmmc-ecc compatible because in
altr_portb_setup() np is the SD/MMC ECC node (found via
of_find_compatible_node(…, “altr,socfpga-sdmmc-ecc”)) so reusing that
felt natural there. I later realised that shifting to
altr,socfpga-s10-ecc-manager is better especially in scenarios where
np could be any child node.

In v3, the compatible is read on the manager node. To avoid repeated
calls (as you have mentioned), I have decided to store it as a `bool
is_s10` in `struct altr_arria10_edac`
