x86: use early_ioremap in __acpi_map_table
__acpi_map_table() effectively reimplements early_ioremap(). Rather
than have that duplication, just implement it in terms of
early_ioremap().
However, unlike early_ioremap(), __acpi_map_table() just maintains a
single mapping which gets replaced each call, and has no corresponding
unmap function. Implement this by just removing the previous mapping
each time its called. Unfortunately, this will leave a stray mapping
at the end.
