ACPI / boot: Correct address space of __acpi_map_table()
Sparse complains about wrong address space used in __acpi_map_table()
and in __acpi_unmap_table().
arch/x86/kernel/acpi/boot.c:127:29: warning: incorrect type in return expression (different address spaces)
arch/x86/kernel/acpi/boot.c:127:29: expected char *
arch/x86/kernel/acpi/boot.c:127:29: got void [noderef] <asn:2>*
arch/x86/kernel/acpi/boot.c:135:23: warning: incorrect type in argument 1 (different address spaces)
arch/x86/kernel/acpi/boot.c:135:23: expected void [noderef] <asn:2>*addr
arch/x86/kernel/acpi/boot.c:135:23: got char *map
