bootmem: reorder interface functions and add a missing one
Impact: cleanup and addition of missing interface wrapper
The interface functions in bootmem.h was ordered in not so orderly
manner. Reorder them such that
* functions allocating the same area group together -
ie. alloc_bootmem group and alloc_bootmem_low group.
* functions w/o node parameter come before the ones w/ node parameter.
* nopanic variants are immediately below their panicky counterparts.
While at it, add alloc_bootmem_pages_node_nopanic() which was missing.
