Use pmap_mapbios() to map ACPI tables on amd64 and i386.
The ACPI table-mapping code used pmap_kenter_temporary() to create mappings, which in turn uses the fixed-size crashdump map. Moreover, the code was not verifying that the table fits in this map, so when mapping large tables we could clobber adjacent mappings. This use of pmap_kenter_temporary() appears to predate support in pmap_mapbios() for creating early mappings, but that restriction no longer applies.
