memmmap: Use biosmem_addr_available rather than vm_page_lookup_pa
The segment code actually has vm_page entries for reserved pages, and
thus memmmap would reject mapping ACPI pages. Taking the information
from biosmem is much more precise, and indeed knows all hardware quirks
which can now be dropped from memmmap.

Fix rejecting the mapping of some pages
The memmmap method may reject some offsets (because it falls in non-device
ranges), so device_map_page has to notice this and report the error.
device_pager_data_request then has to notice as well and report.
