mtd: rawnand: Try not to use the ECC private structures
Most of the time, there is no need to use the software ECC Hamming and BCH algorithms private context to know their configuration. All the data has been stored by their ->init_ctx() hook in the generic NAND ECC engine structure, so use this one when possible.
