xen/debugfs: Add 'p2m' file for printing out the P2M layout.
We walk over the whole P2M tree and construct a simplified view of
which PFN regions belong to what level and what type they are.
Only enabled if CONFIG_XEN_DEBUG_FS is set.
[v2: UNKN->UNKNOWN, use uninitialized_var]
[v3: Rebased on top of mmu->p2m code split]
[v4: Fixed the else if]
