Thanks for the suggestion. This looks a better option. However, I would 
like add here that not only the register offset, but also the register 
bits are different for MMP2 & PXA168. So, the code that would control 
SD/MMC clock will be architecture specific & hence in different 
architecture specific files. Hope this solution looks good to all of you 
in that case as well.

Thanks,

Tanmay
