arch, mm: move definition of node_data to generic code
Every architecture that supports NUMA defines node_data in the same way:
struct pglist_data *node_data[MAX_NUMNODES];
No reason to keep multiple copies of this definition and its forward
declarations, especially when such forward declaration is the only thing
in include/asm/mmzone.h for many architectures.
Add definition and declaration of node_data to generic code and drop
architecture-specific versions.
