mtd: nand: omap: ecc.hwctl: rename omap3_enable_hwecc_bch to omap_enable_hwecc_bch
This patch
- renames omap3_enable_hwecc_bch -> omap_enable_hwecc_bch to keep
nomenclature independent of any device family.
- using '__maybe_unused' instead of `ifdef based conditional compilation
to suppress warning for un-used functions
