driver: mtd: update struct map_info's swap as per map requirement
It is not necessary for all device's maps to be CFI_HOST_ENDIAN. Maps
device can be big endian or little endian.
Currently it is being taken care using CONFIG_MTD_CFI_LE_BYTE_SWAP or
CONFIG_MTD_CFI_BE_BYTE_SWAP i.e. compile time.
Now update struct map_info's swap field based on device characteristics
defined in device tree.
