x86-64, NUMA: simplify nodedata allocation

Browse source

With top-down memblock allocation, the allocation range limits in
ealry_node_mem() can be simplified - try node-local first, then any
node but in any case don't allocate below DMA limit.

Remove early_node_mem() and implement simplified allocation directly
in setup_node_bootmem().
