On x86, __acpi_map_table uses early_ioremap() to create the mapping,
replacing the previous mapping with a new one. Once enough of the
kernel is up an running it switches to using normal ioremap(). At
that point, we need to clean up the final mapping to avoid a warning
from the early_ioremap subsystem.
This can be removed after all the instances in the ACPI code are fixed
that rely on early-ioremap's implicit overmapping of previously
mapped tables.
