Only pgdat and memmap use remap area and there isn't much benefit in
allowing per-node override. In addition, the use of node_remap_size[]
is confusing in that it contains number of bytes before remap
initialization and then number of pages afterwards.
Move remap size calculation for memap from specific NUMA config
implementations to init_alloc_remap() and make node_remap_size[]
static.
The only behavior difference is that, before this patch, numaq_32
didn't consider max_pfn when calculating the memmap size but it's
enforced after this patch, which is the right thing to do.
