Fixing these warnings in the nand driver does not seem to be the correct
approach. Initializing mxc_nand_devtype_data as const seems sane, the
problem is that struct of_device_id expects a void * instead of a const
void *. A patch fixing this is outstanding here:

http://permalink.gmane.org/gmane.linux.drivers.devicetree/15069

(this will also fix the other sparse warnings from this driver)

I asked Uwe to resend this.

So I only added Shawns Ack to the arm-i.MX part, you can pull this into
the mtd tree:
