    mtd: brcmnand: Fix misuse of IS_ENABLED
    
    While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
    for other symbols such as __BIG_ENDIAN that is provided directly by
    the compiler.
    
    Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.
    
    Fixes: 27c5b17cd1b1 ("mtd: nand: add NAND driver "library" for Broadcom STB NAND controller")
