[XFS] Remove the BPCSHIFT and NB* based macros from XFS.
The BPCSHIFT based macros, btoc*, ctob*, offtoc* and ctooff are either not used or don't need to be used. The NDPP, NDPP, NBBY macros don't need to be used but instead are replaced directly by PAGE_SIZE and PAGE_CACHE_SIZE where appropriate. Initial patch and motivation from Nicolas Kaiser.
