x86-32, numa: Calculate remap size in common code
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.
