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.
