FRAME_POINTER is defined in lib/Kconfig.debug, it is unnecessary to redefine it in arch/arm64/Kconfig.debug. Actually, the one defined in arm64 directory is never used. This adds a dependency on DEBUG_KERNEL for building with frame pointers. ARM64 depends on frame pointer to get correct stack backtrace and need FRAME_POINTER kconfig option enabled all the time. However, currect implementation makes it could be disabled, so force it to be selected by ARM64.
