Hehe, this one is a bit tricky. Indeed MACH_MXLADS isn't used directly
anywhere. Nevertheless having CONFIG_MACH_MXLADS defined makes
machine_is_mxlads() become true when the kernel is started with a
machine id of 1851.

machine_is_mxlads() is unused in the kernel, so this patch indeed
doesn't hurt. Anyway, the code is correct currently, so I suggest
keeping it until the mx[1l]ads is either removed or converted to
devicetree.
