[PATCH v2 01/25] qcom: mtd: nand: fixed config error for BCH

[Abhishek Sahu <absahu@codeaurora.org>]

The configuration for BCH is not correct in the current driver.
The ECC_CFG_ECC_DISABLE bit defines whether to enable or disable the
BCH ECC in which

	0x1 : BCH_DISABLED
	0x0 : BCH_ENABLED

But currently host->bch_enabled is being assined to BCH_DISABLED.
