arm64: mm: replace 'block_mappings_allowed' with 'page_mappings_only'

Browse Source 
In preparation of adding support for contiguous PTE and PMD mappings,
let's replace 'block_mappings_allowed' with 'page_mappings_only', which
will be a more accurate description of the nature of the setting once we
add such contiguous mappings into the mix.
