ACPI: Use ioremap_cache()
Although the temporary boot-time ACPI table mappings were set up with CPU caching enabled, the permanent table mappings and AML run-time region memory accesses were set up with ioremap(), which on x86 is a synonym for ioremap_nocache(). Changing this to ioremap_cache() improves performance as seen when accessing the tables via acpidump, or /sys/firmware/acpi/tables. It should also improve AML run-time performance. No change on ia64.
