[PATCH] ide: Allow IDE interface to specify its not capable of 32-bit operations

Browse Source 
In some embedded systems the IDE hardware interface may only support 16-bit
or smaller accesses.  Allow the interface to specify if this is the case
and don't allow the drive or user to override the setting.
