mtd: nand: omap: ecc.calculate: refactor omap_calculate_ecc_bch for BCHx_HW ecc-scheme
OMAP NAND driver supports multiple flavours of BCH4 and BCH8 ECC algorithms.

This patch refactors omap_calculate_ecc_bch() so that
- separate out ecc-scheme specific code so that common-code can be reused
between different implementations of same ECC algorithm.
- new ecc-schemes can be added with ease in future.
