Some of the N770's MMC configuration options seem to have been  
dropped. This patch adds them back in again.

Note that only the .ocr_mask change was /critical/, but I've added the  
.max_freq setting back as well, as the original sources had it. Can  
anyone confirm if this is unnecessary?

Secondly, there is support in the original code for a 4wire/higher  
speed mode. As I don't have the requisite N770 hardware (I think it  
was a rev2 N770?) to test this, I can't really add it back.
