x86-64, NUMA: Unify use of memblk in all init methods

Make both amd and dummy use numa_add_memblk() to describe the detected
memory blocks.  This allows initmem_init() to call
numa_register_memblk() regardless of init method in use.  Drop custom
memory registration codes from amd and dummy.

After this change, memblk merge/cleanup in numa_register_memblks() is
applied to all init methods.

As this makes compute_hash_shift() and numa_register_memblks() used
only inside numa_64.c, make them static.
