The consensus on the call today was that this is the best approach.  
Not only do you have a single interface that can be used with  
different platforms, it will also play out nicely when trying to  
tackle the multiple ADCs on a single platform issue. E.g., the MDA300  
can provide its own AdcConfigure<mda300_adc_config_t> while the  
atm128 can provide the AdcConfigure<atm128_adc_config_t>. Generic  
components above that want to be able to be ADC-independent merely  
need to be generic components that have this type as a parameter.  
They cannot modify the structure regardless. so this works well.
