ACPICA: Remove obsolete acpi_os_validate_address interface
This interface is no longer necessary. Requests should be validated on a per-field basis, not on the entire operation region. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
