The arch specific __acpi_map_table can be wrapper around either
early_memremap or early_ioremap. But early_memremap
routine works with normal pointers whereas __acpi_map_table expects
pointers in iomem address space. This causes kernel test bot to fail
while using the sparse tool. Fix the issue by using early_ioremap and
similar fix done for __acpi_unmap_table.
