efi/unaccepted: Make sure unaccepted table is mapped
Unaccepted table is now allocated from EFI_ACPI_RECLAIM_MEMORY. It
translates into E820_TYPE_ACPI, which is not added to memblock and
therefore not mapped in the direct mapping.
This causes a crash on the first touch of the table.
Use memblock_add() to make sure that the table is mapped in direct
mapping.
Align the range to the nearest page borders. Ranges smaller than page
size are not mapped.
Fixes: e7761d827e99 ("efi/unaccepted: Use ACPI reclaim memory for unaccepted memory table")
