s390/pgtable: Add missing hardware bits for puds, pmds 



Add the table type and ACCF validity bits to _SEGMENT_ENTRY_BITS and
_SEGMENT_ENTRY_HARDWARE_BITS{,_LARGE}.

For completeness, introduce _REGION3_ENTRY_HARDWARE_BITS_LARGE and
_REGION3_ENTRY_HARDWARE_BITS, containing the hardware bits used for
large puds and normal puds.
