We don't need to update fsl_ifc_sram_init() as fsl_ifc_sram_init is called from the fsl_ifc_chip_init which configures the ifc_ctrl->cs_nand with correct value based on the chip-select under initialization.

Corrected the chip selection in IFC_NAND_CSEL register. Due to this issue in multi-chip nand use-case, IFC was always pointing to the last probed chip even though the user select another device through "nand device" command.
