bootmem: factor out the marking of a PFN range
Introduce new helpers that mark a range that resides completely on a node
or node-agnostic ranges that might also span node boundaries.
The free/reserve API functions will then directly use these helpers.
Note that the free/reserve semantics become more strict: while the prior
code took basically arbitrary range arguments and marked the PFNs that
happen to fall into that range, the new code requires node-specific ranges
to be completely on the node. The node-agnostic requests might span node
boundaries as long as the nodes are contiguous.
Passing ranges that do not satisfy these criteria is a bug.
