Add a new at91rm9200ek_mmc board (based on at91rm9200ek board) which enables
mmc0/slot0.

no for multiple dts

this need to handle at user space level

You mean, by controlling the regulator using the sysfs interface, or by 
loading
only the appropriate driver ?

What if both drivers are loaded (or not compiled as modules) ?
This will lead to one device being unusable (and maybe even worst)...

Please explain what you had in mind ?
