pekon gupta 6e562b1106 mtd: nand: omap: optimized chip->ecc.correct() for H/W ECC schemes 
chip->ecc.correct() is used for detecting and correcting bit-flips during read
operations. In omap-nand driver it implemented as:
(a) omap_correct_data(): for h/w based ECC_HAM1 scheme
(b) omap_correct_data_bch() + CONFIG_NAND_OMAP_ECC_BCH8_CODE_HW_DETECTION_SW
	for ECC_BCH8 scheme using GPMC and software lib/bch.c
(c) omap_correct_data_bch() + CONFIG_NAND_OMAP_ECC_BCH8_CODE_HW
	for ECC_BCH8 scheme using GPMC and ELM

This patch updates (c)
- checks for calc_ecc[]==0x00 so that error_correction is not required for
  known good pages.
- adds scalability for other ECC_BCHx scheme by merging following
  omap_rotate_ecc_bch() + omap_fix_errors_bch() => omap_correct_data_bch()
- fixing logic for bit-flip correction based on error_loc[count]
