    mtd: lpddr: fix Kconfig dependency, for I/O accessors
    
    Not all architectures implement a writel_relaxed() accessor. Hopefully
    this will change eventually, but for now, this means lpddr2_nvm.c can't
    compile on some architectures.
    
    Let's add an ARM dependency for now, and leave a comment so maybe we can
    change this in the future.
