While looking for the fixes tag this would require for the dts, I
realised that this is just another of the properties that pre-dated
my involvement with the dt. I think it's in the same category as
ti,fifodepth & was just copied from somewhere else.
I think rather than rename it, it should just be outright deleted.
cd-debounce-delay-ms depends on cd-gpios, and we don't have any
GPIOs wired to the sdcard.

Thanks,
Conor.
