"for SDIO slots" is somewhat misleading; nearly all controllers only
do one slot/device per controller. The designware controller can do
multiple slots, and that adds a bit of driver and binding complexity
for something that seemingly not a single vendor has actually
implemented.

So we can likely assume to keep these reset/power/clock lines per host
controller, no need to add a slot construct.

Actually, the atmel chips have two slots per controller so it would
probably be better to think about that now.

Moreover, we have DT description for this.
Cf. Documentation/devicetree/bindings/mmc/atmel-hsmci.txt
