OK.

Correction! I had the order wrong.
>From the RZ/AH1 Hardware manual (51.4 Interrupt Requests)
#1. MMC0,299: Card detection interrupt
#2. MMC1,300: Error/timeout interrupt
#3. MMC2,301: Normal operation interrupt

OK. I have no objections to adding it to DT and renesas,mmcif.txt and not touching sh_mmcif.c (just letting it ignore the 3rd value).
If someone in the future wants to code up card detect....they are welcome to it ;)
