    the new early_res.c is extension to lmb.

    it will
    1. add find_lmb_area
    2. add check_double_region array with find_lmb_area
    3. free_early and reserve_early is wrapper for lmb_free, and lmb_reserve with array size checking
    4. some other generizing function like lmb_register_active_regions and lmb_hole_size that could be all lmb users.

    so it is seperated file at point.

    if lmb guys are happy, we can merge early_res.c and lmb.c. just put them in one file.

    Thanks

    Yinghai
