x86: use early_ioremap in __acpi_map_table

Browse Source 
__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.
