mtd: add ecc_strength fields to mtd structs

Browse Source 
This adds 'ecc_strength' to struct mtd_info.  This stores the maximum number of
bit errors that can be corrected in one writesize region.

For consistency with the nand code, 'strength' is similiarly added to struct
nand_ecc_ctrl.  This stores the maximum number of bit errors that can be
corrected in one ecc step.
