s390/mm: Abstract gmap notify bit setting
Currently we use the software PGSTE bits PGSTE_IN_BIT and PGSTE_VSIE_BIT to notify before an invalidation occurs on a prefix page or a VSIE page respectively. Both bits are pgste specific, but are used when protecting a memory range. Let's introduce abstract GMAP_NOTIFY_* bits that will be realized into the respective bits when gmap DAT table entries are protected.
