acpi: remove final __acpi_map_table mapping before setting acpi_gbl_permanent_mmap
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.
