mtd: nand: qcom: fix config error for BCH



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 assigned to BCH_DISABLED.
