mtd: nand: omap_elm: use bch_type instead of nibble count to differentiate between BCH4/BCH8/BCH16
ELM hardware engine support ECC error detection for multiple ECC strengths like
+------+------------------------+
|Type | ECC syndrome length |
+------+------------------------+
|BCH4 | 6.5 bytes = 13 nibbles |
|BCH8 | 13 byte = 26 nibbles |
|BCH16 | 26 bytes = 52 nibbles |
+------+------------------------+
Current implementation of omap_elm driver uses ECC syndrom length (in 'nibbles')
to differentiate between BCH4/BCH8/BCH16. This patch replaces it with 'bch_type'
