We have generic place & helpers for storing platform driver data so
there is no reason for using custom priv pointer.

This allows cleaning up struct bcma_sflash from unneeded fields.

Kalle: This is mtd focused patch, so I guess it should go through mtd tree. Do
       you find bcma change important enough to care to Ack it? :)

Sure :)

Feel free to take the patch via mtd tree, I'm not expecting to see any
conflicts with this patch. For the bcma part:
