We already have the inverse of this with "cap-mmc-highspeed".

The only potential problem is it will need to be added to existing DTs 
if you start disabling high speed by default. Maybe that's not an issue 
for users of the Arasan driver.

Otherwise, you should determine this with a more specific compatible 
string.
