I do not think so. :)

I think the onfi_feature() is useful in the future.
I only add the two feauture for this helper:
   [1] 16-bit and
   [2] extended parameter page

But in actually, we may add more feature to this helper, such as 
_synchronous_.
For example, some driver may support the synchronous mode for the ONFI nand.
We can use this onfi_feature() in the driver to check if the onfi nand 
supports this
synchronous feature.

Add this helper makes the code more readable, though we introduce a 
little redandancy.

thanks
Huang Shijie
