s390/facilities: cleanup PFMF and HPAGE machine facility detection
MACHINE_HAS_PFMF and MACHINE_HAS_HPAGE actually have the same semantics:
the cpu has the EDAT1 facility installed in zArch mode. So remove one
of the feature flags in machine_flags and rename the other one to EDAT1.
The two old macros simply get mapped to MACHINE_HAS_EDAT1.
