arm64/mm: Add remaining ID_AA64MMFR0_PARANGE_ macros

Browse source

Currently there are macros only for 48 and 52 bits parange value extracted
from the ID_AA64MMFR0.PARANGE field. This change completes the enumeration
and updates the helper id_aa64mmfr0_parange_to_phys_shift(). While here it
also defines ARM64_MIN_PARANGE_BITS as the absolute minimum shift value PA
range which could be supported on a given platform.
