If the write protect pad of the controller is not connected to the write protect pin of the slot, the driver should be notified of this condition so that incorrect check for write protection by reading the WRTORT register can avoided. The get_ro platform callback can be used for in such cases, but with device tree support enabled, such platform callbacks cannot be supported. Add a new quirk for notifying the driver about the missing write protect line so the driver can assume that the card write protection is disabled.
