    Fix fallout from migration from alloca() to malloc() in the previous.

    of_compatible() is used at least for macppc in very early boot stage
    where malloc() is still not available.

    Therefore, for small (<= OFW_MAX_STACK_BUF_SIZE = 256) buffer, use
    statically allocated one in the stack. For larger one, we continue to
    use malloc() but KASSERT(!cold) is added for sure.

    Fix boot failure for macppc reported by martin:
