[PATCH v2 7/7] mn10300: add early_init_dt_*

[Sudip Mukherjee <sudipm.mukherjee-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

While building it failed with:
undefined reference to `early_init_dt_alloc_memory_arch'
undefined reference to `early_init_dt_add_memory_arch'

Added the function after seeing them in x86.
