mm: remove PFN_DEV, PFN_MAP, PFN_SPECIAL, PFN_SG_CHAIN and PFN_SG_LAST
The PFN_MAP flag is no longer used for anything, so remove it. The
PFN_SG_CHAIN and PFN_SG_LAST flags never appear to have been used so also
remove them. The last user of PFN_SPECIAL was removed by 653d7825c149
("dcssblk: mark DAX broken, remove FS_DAX_LIMITED support").
Users of PFN_DEV were removed earlier in this series by "mm: Remove
remaining uses of PFN_DEV".
